Jinwoo Hong fb322046e8 skills: rewrite and trim the seven non-orchestration guides (#19128)
* skills: rewrite the seven non-orchestration guides to one outcome-first standard

Every guide leads with Result / Done / Safe failure, states conditions instead of case lists, keeps one done bar and one autonomy envelope, and loads references at the point of use via `skills get <topic> --full`. orca-cli drops from 424 to 260 always-loaded lines with three references; orca-per-workspace-env from 794 to 397 with five.

Defects fixed in shipped guides: `emulator camera` (no such command), iOS `permissions` (backend refuses it), Android pane described as in development, `relayGracePeriodSeconds: 0` documented as immediate teardown (it is unbounded), doctor `ok: true` hiding `warn`, an SSH exemplar setting both `jumpHost` and `proxyCommand`, a provisioned-root fetch from `origin`, and the Linear unconfirmed-write rule keyed on four verbs when ten emit it.

The resolver ladder, placeholder rule, and older-binary fallback shared by every installable SKILL.md now come from one skill-stubs/_shared/cli-resolution.md fragment composed by the generator, which also bundles per-guide references into --full. New guards: every ORCA invocation and flag resolves against COMMAND_SPECS, descriptions carry no angle-bracket tokens, reference routing is checked both ways, and an always-loaded size ratchet (300 lines) that guides may leave but never join.

* skills: address review on the SSH recipe and the parity guard

- ssh-host create script: route the bootstrap ssh through the chosen jump host or proxy command, refuse both at once, use StrictHostKeyChecking=accept-new instead of a blind ssh-keyscan append, and pass gh_token/project_root/repo_url/repo_ref to the remote bash via printf %q so a quote in a value cannot break out of the command.
- per-workspace-env envelope: the step-10 workspace test the user asked for is no longer forbidden by the same paragraph.
- linear guides: name the full verb, ORCA linear list-issues.
- parity guard: a prefix reference such as ORCA linear --help or ORCA emulator --webcam now has its flags checked against every command under that prefix; only an exact path or an explicit ... was checked before.

* skills: tighten prose in the seven rewritten guides

Shorter outcome spines, one idea per sentence, no restated rationale after a rule. No rule, command, or pinned phrase changes; 47 net lines fewer across the guides and references.

* skills: route orca-cli and per-workspace-env gates through --reference

Both guides told agents to load --full at a gate because the per-reference
selector did not exist when they were written. Now that main serves
`skills get <topic> --reference references/<file>.md`, load only the
named file and keep --full as the fallback for an older CLI, matching the
orchestration kernel.

* skills: drop outcome-spine boilerplate from the CLI-wrapper guides

The Result/Done/Safe-failure preambles and Next Action closers restated
rules the body already carries. Agents stop fine without them, and for
a CLI wrapper the command surface is the guide. Keeps the one substantive
rule computer-use's Done block added (never report unverified as success)
inside Action Rules. orchestration and per-workspace-env keep theirs:
those are multi-step workflows where the done bar is load-bearing.

(cherry picked from commit 44a74baf73)

* skills: trim the guides and stubs to what agents actually need

- Drop the Result/Done/Safe-failure preambles and Next Action closers from
  the six CLI-wrapper guides; the one substantive rule (never report an
  unverified computer-use action as success) moves into Action Rules.
- Drop the 'guide may be stale, trust --help' lines: the guide is served by
  the binary that runs the commands, so it cannot be stale relative to it.
- Drop the status --json / open --json preflight from every guide; the stub
  no-guessing paragraph now says to start Orca only when a command reports
  it is not running.
- Cut the ORCA placeholder paragraph in each guide to one line that points
  back at the stub's resolution.
- Trim the orchestration, orca-cli, and computer-use descriptions to trigger
  phrases plus one line of scope.
- Remove the older-binary fallback section from every stub (and its two
  shared blocks); a binary without skills get gets one sentence.
- Remove the guide size ratchet test.

## ELI5

Orca ships eight skill guides that agents read before running the CLI. Seven of them (everything except `orchestration`, which #16904 rewrites) were command catalogs that had drifted from the binary. This PR rewrites them so an agent reads the outcome, the done bar, and the safe-failure rule first, loads reference material only at the step that needs it, and never sees a command or flag the installed CLI does not define.

## What changed

- **Seven guides rewritten** to one standard: outcome spine first (Result / Done / Safe failure), conditions instead of case lists, one done bar, one autonomy envelope, references loaded at the point of use via `skills get <topic> --full`, every runnable invocation spelled `ORCA`. `orca-cli` is 424→260 always-loaded lines with three references (browser, automations, publishing); `orca-per-workspace-env` is 794→397 with five (provider-vercel, ssh-host, docker-ssh, windows-scripts, failure-modes).
- **Defects fixed in shipped guides:** `emulator camera` (no such command), iOS `permissions` (backend refuses it), Android pane described as "in development" (shipped in June), `relayGracePeriodSeconds: 0` documented as immediate teardown (it is unbounded), doctor `ok: true` hiding `warn`, an SSH exemplar setting both `jumpHost` and `proxyCommand`, a provisioned-root fetch from `origin`, the Linear unconfirmed-write rule keyed on four verbs when ten emit it. Linear and emulator descriptions dropped embedded commands and angle-bracket placeholders (651→329, 732→404 chars).
- **Generator bundles references.** `skill-guides/<name>/references/*.md` is appended to `--full`; `skills get` help says compact by default, full with references.
- **Stubs single-authored.** The resolver ladder, placeholder rule, and older-binary fallback shared by all eight installable `SKILL.md` files come from one `skill-stubs/_shared/cli-resolution.md` fragment composed by the generator. Projections were byte-identical before the content fixes.
- **Guards:** every `ORCA <cmd>` and flag in every guide and reference resolves against `COMMAND_SPECS` (this found the camera defect); descriptions ≤1024 chars with no angle-bracket tokens; reference routing checked both directions; an always-loaded size ratchet (300 lines) that guides may leave but never join. `orchestration` (440 lines on main) is recorded as an exception until #16904 lands its kernel.

## Relationship to #16904

Split out of #16904 so that PR carries only the orchestration guide. On main, `terminal send` has no `--wait-submit` / `--retry-request` and the orchestration kernel still carries the resolver ladder and worktree-selector rule, so this branch pins `accepted: true` for handoff receipts and leaves the orchestration pins where main has them. The merge in either direction is mechanical: #16904 rebased on this becomes a one-file `orchestration.md` change plus dropping the two exceptions.

## Standard

Compound Engineering's portable skill-authoring guidance (outcome spine, conditions not cases, pinned fragile commands with an ordered hatch, references at point of use). NVIDIA SkillEvaluator Tier 1 (`schema,pii,license,quality,unicode,lint`) was run on every guide; its deterministic checks pass, its template nudges (Instructions/Examples sections, 50–150 char descriptions) do not apply to Orca's stub architecture and were not applied.

## Testing

- `pnpm typecheck:tsc:cli` clean; `check:code-quality:changed` and `check:react-doctor:changed` 0 findings
- `pnpm verify:bundled-skill-guides` and skill-bundle manifest verify clean
- vitest over `config/scripts`, `src/cli/skill-guide-cli-parity.test.ts`, `src/cli/skills.test.ts`, `src/cli/specs/skills.test.ts`, `src/cli/help.test.ts`, `src/main/skills`: 240 files / 2,019 pass
- Live smoke on the built CLI of every `skills get <topic>` and `--full`, every emulator, linear, and vm verb named in the guides, and every projection's resolver, GNOME warning, and bounded fallback (done on the #16904 branch before the split; the guide bodies are identical here except the send-receipt vocabulary noted above)

## Deferred product decisions

Merging `orca-emulator` and `orca-emulator-android` into one skill with a platform branch; collapsing `linear-tickets` to a guide alias; a `skills get --reference <name>` selector so a gate table can load one file; a fresh-agent routing eval before trimming the `orca-cli` (1,015 chars) and `orchestration` descriptions, whose quoted triggers each fixed a routing misroute.

Review follow-up: the emulator guides still instructed literal
`orca emulator ...` in sh fences with no Linux disambiguation, so on
unmanaged Linux they could launch the GNOME screen reader — the exact
failure the executable-selection preamble prevents. Both emulator
guides now carry the preamble and ORCA placeholder across fences,
tables, and prose, and the cross-platform safety test covers all four
converted guides. Also replaces computer-use's "unless a block names a
shell" carve-out, which contradicted its own POSIX example, with the
unconditional placeholder rule.

42b2ecc5c6 feat(emulator): Android emulation via scrcpy (cross-platform, iOS parity) (#6434)
* docs: add Android emulation design spec

Adds the design for first-class Android emulator support as a cross-platform
peer of the iOS simulator feature: an extracted EmulatorBackend interface
(iOS + Android), full AVD lifecycle management via the Android SDK, a live
scrcpy H.264 pane decoded in-renderer with WebCodecs, the full control surface
(tap/gesture/type/buttons/rotate), accessibility tree, app install/launch,
runtime permissions, logcat, and a dedicated orca-emulator-android skill.

* refactor(emulator): add EmulatorBackend interface + backend/codec session tags

First step of multi-backend emulator support: introduce the EmulatorBackend
type and tag each session with its backend kind + stream codec, defaulting to
ios/mjpeg so existing serve-sim behavior is unchanged.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* refactor(emulator): extract IosEmulatorBackend and make the bridge a router

Move the serve-sim/simctl device + helper + input mechanics out of
EmulatorBridge into IosEmulatorBackend (implementing EmulatorBackend). The
bridge now owns the session registry and lifecycle orchestration and routes
each command to the backend that owns the target device. iOS behavior is
unchanged; the existing bridge tests pass untouched and the backend gains its
own input-op coverage.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(emulator): add pure Android leaf modules (sdk/adb/avd/scrcpy/input/ax)

Dependency-injected building blocks for the Android emulator backend, each unit-
tested in isolation: SDK + tool discovery, adb device/output parsing, AVD list +
boot arg building, scrcpy control-socket byte encoders, normalized<->pixel +
keycode mapping, and a uiautomator XML accessibility-tree parser. Not yet wired;
AndroidEmulatorBackend composes these in the next phase.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* refactor(emulator): gate availability on the iOS backend + lock it with tests

inspectEmulatorAvailability now decides iOS host support via the registered iOS
backend instead of a bare platform literal, routing the decision through the
multi-backend seam. Output shape and all messages are unchanged (the settings
pane still reads simctl/serveSim). Adds the previously-missing regression tests
covering the unsupported, ready, no-devices, and tool-failure paths.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(emulator): add Android app/permissions/logcat arg builders

Pure adb arg-builders + a logcat line parser for app install/launch, runtime
permission grant/revoke/reset, and logcat capture. Unit-tested in isolation;
wired into AndroidEmulatorBackend's capability verbs in a later phase.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(emulator): AndroidEmulatorBackend device management + unified device list

Adds the Android backend (registered alongside iOS in the bridge): SDK-gated
host support, device/AVD discovery and merge, AVD boot + boot-completion wait,
shutdown, and tap/swipe/type/button/rotate/exec via `adb shell input` so control
works without the scrcpy server (the live H.264 stream lands in the streaming
phase). Surfaces everything through a new cross-platform `orca emulator devices`
command (RPC emulator.listDevices -> bridge.listAllDevices) with a platform
column. Device inventory is split into its own module to keep files focused.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(emulator): Android capability verbs (install/launch/permissions/ax/logcat)

Wires the Android capability operations into AndroidEmulatorBackend and exposes
them through a capability-gated bridge router (runCapability), RPC, and CLI:
- orca emulator install/launch/permissions/ax/logcat
Capabilities are advertised per backend; calling one on a backend that lacks it
(e.g. iOS) fails with emulator_unsupported instead of a silent no-op. Input ops
and capability ops are split into focused modules to keep files under the
line cap; the runtime shares one target-param type.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* docs(skill): add orca-emulator-android skill + cross-ref from iOS skill

Documents the cross-platform Android emulator control surface (devices, input,
hardware buttons, rotate, install/launch, permissions, ax, logcat) driveable via
the orca CLI today, and notes the live visual pane is in development. Points the
iOS skill's "when not to use" at the new Android skill.

* feat(emulator): Android live-pane streaming scaffolding (scrcpy + WebCodecs)

Builds the H.264 video path as scaffolding: scrcpy frame/codec-meta parsing,
server-deploy arg builders, control-protocol encoders (committed earlier), the
stream session (server + sockets), a video pub/sub registry, the
emulator:videoStream* IPC channel, and a renderer WebCodecs->canvas hook. Pure
framing/deploy/registry are unit-tested; the socket/WebCodecs/jar integration is
clearly flagged UNVERIFIED and the remaining wiring (startSession, preload,
pane codec branch, packaging the jar) is documented in
docs/android-emulation-streaming.md.

* chore(emulator): add diagnostic probes for Android testing

Adds an emulator-probe logger (console + temp file at
os.tmpdir()/orca-android-emu-probe.log) and wires probes at four layers so
errors surface during manual testing: every emulator.* RPC call + error (RPC
dispatcher), every adb/emulator command + non-zero exit (command runner), and
the scrcpy session + video-stream IPC lifecycle. Temporary diagnostics; remove
or gate behind a flag once the Android pane is validated.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(emulator): show Mobile Emulator settings cross-platform + aggregate Android availability

The Mobile Emulator settings section is no longer macOS-gated (Android works on
Windows/Linux), and inspectEmulatorAvailability now aggregates the iOS and
Android backends: Android devices/AVDs appear in the device list and a host
without iOS gets the Android setup message instead of "requires macOS".

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): show Mobile Emulator sidebar nav entry on non-mac desktops

The settings sidebar nav registered the Mobile Emulator entry behind isMac, so
it stayed hidden on Windows/Linux even after the section content was ungated.
Widen it to showDesktopOnlySettings to match the section.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(emulator): wire Android startSession to scrcpy + client-downloaded jar

AndroidEmulatorBackend.startSession now boots the device, ensures the scrcpy
server jar (downloaded by the client into the per-user cache on first use, not
bundled), starts a ScrcpyStreamSession, and feeds its H.264 frames to the video
registry; stopHelperForDevice tears it down. Sessions carry their backend kind
so worktree-active routing picks the right backend. Boot, host SDK discovery,
and the stream starter are split into focused modules to stay under the line cap.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): stop the iOS backend from claiming Android devices off-mac

iOS ownsDevice now returns false unless the host supports it, so on Windows an
Android serial routes to the Android backend instead of erroring with
"requires macOS". Backend-for-device fallback prefers a host-supported backend.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): scrcpy scid 31-bit + retry video socket until server delivers

Two fixes validated against a real emulator: scrcpy parses scid as a signed
32-bit hex int, so mask to 31 bits + pad to 8 digits (8-byte values overflowed
and the server exited). And adb accepts the forwarded TCP connection before the
server's abstract socket exists then resets it, so retry the video socket until
it actually delivers the dummy byte before connecting control. H.264 meta now
arrives (576x1280). Adds socket/server-exit diagnostics probes.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(emulator): render the Android H.264 pane via WebCodecs

Wires the live Android pane end-to-end: preload exposes emulator video stream
APIs; the pane's device list uses the unified emulator.listDevices (Android +
iOS); and emulator-screen-stream-content renders a WebCodecs <canvas> for
scrcpy:// sessions (H.264, SPS/PPS prepended to the first keyframe) instead of
the MJPEG <img>. The video hook reports the stream size for the device frame.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(emulator): buffer the current GOP for late video subscribers

The renderer subscribes after attach already started the scrcpy stream, so the
registry now caches the current GOP (keyframe + following deltas) alongside the
codec meta and config, and replays it on subscribe. A pane opened mid-stream
decodes from the keyframe immediately instead of showing black until scrcpy's
next periodic keyframe (~10s). Refreshes the now-validated session doc comment.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): show New Mobile Emulator tab action off macOS

The tab create menu and its dropdown item gated the New Mobile Emulator action
on isMacOs, hiding it on Windows/Linux where Android emulation is now supported.
Gate on mobileEmulatorEnabled + onNewSimulatorTab (already cross-platform) so
the action appears wherever a mobile emulator backend is available.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): open the Mobile Emulator tab off macOS

openMobileEmulatorTab and ensureSimulatorTab both returned null unless the host
was macOS, so the New Mobile Emulator action no-opped on Windows/Linux even
though the menu entry showed. Drop the isMacOsHost early-returns; the
mobileEmulatorEnabled setting and backend availability already gate the feature.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): resolve a default attach device across backends

emulatorAttach with no device fell back only to the iOS listSimulators picker
(empty on Windows/Linux), so the pane's no-device launch flow errored. Extract
resolveDefaultAttachDevice: iOS default first, else the first booted (else
first) device across host backends, so Android attaches without an explicit
device. Split into its own module to stay under the line cap.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): render the pane off macOS instead of an unavailable wall

EmulatorPane short-circuited to the "macOS only" EmulatorUnavailablePane on any
non-Mac host, blocking the now-working Android pane. Always render the pane
content; its device discovery and error surface handle a missing backend.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): let attach boot a shut-down AVD with a stale active session

getReusableActiveForWorktree called resolveDeviceId on the requested device,
which throws for a not-yet-booted Android AVD, aborting the attach. Guard it so
a resolve failure means "not the active device" and the attach falls through to
a fresh boot — so picking a shut-down AVD in the pane and hitting Connect boots
it via ensureBooted instead of erroring.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): launch the AVD detached instead of via execFile

bootAndroidDevice started the emulator through the command runner (execFile with
a timeout + 1MB stdout maxBuffer), which kills the long-running, verbose emulator
process — so booting an AVD from the pane never actually came up. Spawn it
detached with no stdio and unref it so it outlives the call, mirroring how the
scrcpy server is launched.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): dedupe concurrent attaches into one scrcpy stream

Extract AndroidStreamController to own the per-serial scrcpy lifecycle and
dedupe starts: concurrent attaches (e.g. the pane's auto-attach racing the tab
launch) now share one in-flight start and reuse the live stream instead of
spawning a second scrcpy server that fights for the port and kills the first.
Also initialize the registry GOP buffer in register() (latent type error).

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): boot the AVD headless without a console window

The detached spawn opened a Windows console (showing the emulator's verbose
qemu/netsim logs) and a redundant native emulator window. Pass windowsHide and
run the emulator with -no-window so it boots headless — the scrcpy pane is the
view, matching how iOS hides Simulator.app.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): boot the AVD with a hidden console, not detached

detached: true sets DETACHED_PROCESS, which gives the console-subsystem emulator
no console — so it and its qemu/netsim children pop their own visible cmd window
that windowsHide can't suppress. Drop detached and rely on windowsHide
(CREATE_NO_WINDOW = hidden console) + unref; spawn already keeps it alive past
the launch call, and managed emulators are shut down on app quit.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): keep Android emulators alive when switching devices

Attaching a different device shut down the active one (shutdownDevice: true),
which for Android meant killing the running emulator and cold-booting the target
(~60s) on every switch — and switching back. Add bridge.stopActiveForSwitch:
Android emulators stay running for instant switch-back, while iOS simulators are
still replaced. Switching to an already-running emulator is now immediate.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* perf(emulator): only resize the video canvas when dimensions change

The decoder output handler set canvas.width/height on every frame, which
reallocates the canvas backing store and forces an object-contain reflow each
frame — a needless per-frame cost. Resize only when the frame dimensions
actually change.

* feat(emulator): genericize copy + add Android Studio setup link

Replace iOS-only wording (Xcode/Simulator/iPhone) in the pane and settings with
backend-neutral copy so Android reads correctly on every platform. When no
emulator is available, the Mobile Emulator settings now show a "Download Android
Studio" link plus setup guidance (ANDROID_HOME / default install path). Removes
the now-unused, macOS-only EmulatorUnavailablePane.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(emulator): show emulator SDK status in settings

The backend availability now reports the resolved Android SDK path, aggregated
into emulator.availability as an `android` block. The Mobile Emulator settings
render an "Emulator SDKs" card showing Android SDK (detected at <path> / not
found, with a Download Android Studio link) and, on macOS, iOS Simulator (Xcode)
status — mirroring the agent-control card.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(emulator): locate a custom Android SDK folder from settings

Add an androidSdkPath setting and a "Locate SDK folder…" / Clear action in the
emulator SDK status card. The path is applied as the highest-priority discovery
candidate (falls back if invalid), and the backend's SDK is re-resolved on use
via a new AndroidSdkState — so locating or installing the SDK takes effect on
Refresh without restarting Orca. Guards the status card against older runtimes.

* fix(emulator): settle the scrcpy video socket once to stop retry storms

A failed TCP connect emits both 'error' and 'close', so retry ran twice and
scheduled openVideoSocket(attempt+1) twice — fanning out into an exponential
connection storm while waiting for the server to start listening. A runaway
chain could then hit attempt 100 and fail/close a stream that had already
connected. Replace the delivered flag with a single settled latch so each
socket retries (or delivers) exactly once.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(emulator): address CodeRabbit review findings

- avd-boot: handle spawn 'error' (an unhandled ChildProcess error crashed the
  main process); validate the target is a known AVD before launching.
- capability-ops: propagate adb non-zero exits for launch/permission/logcat and
  check the uiautomator dump before reading (avoids stale XML).
- scrcpy-video-registry: actually replay the buffered GOP on subscribe so late
  subscribers decode immediately.
- android-sdk-state: re-resolve host discovery every call so a changed SDK path
  takes effect live (no restart).
- android-sdk-discovery: require both adb and the emulator binary.
- emulator-bridge: fall back to the platform-primary backend (Android off-mac)
  so setup errors aren't iOS/CoreSimulator on Windows/Linux.
- scrcpy-server-download: dedupe concurrent first-use downloads + add a timeout.
- scrcpy-stream-session: idle-socket connect timeout; surface control-socket
  errors instead of swallowing them.
- android-exec: pass the whole command so the device shell parses quotes/pipes.
- avd-manager: match emulator log prefixes exactly (keep AVD names like
  PixelWARNINGTest).
- permissions: `pm reset-permissions` is global and takes no package argument.
- stream controller/starter: drop stale handles for dead streams; idempotent
  teardown. use-emulator-video-stream: stopVideoStream returns Promise.

* fix(emulator): populate the GOP buffer and reuse live scrcpy streams

Self-audit follow-ups in the same class as the CodeRabbit GOP-replay finding:

- scrcpy-video-registry: pushFrame never wrote to entry.gop, so the replay
  loop added for late subscribers iterated an empty array — a no-op. Build the
  GOP on ingest (start at each keyframe, append following deltas; don't buffer
  deltas before the first keyframe). Adds tests for population, reset, and the
  pre-keyframe guard.
- android backend: isSessionReusable was stubbed to always return false with a
  "no persistent stream yet" note, but scrcpy streams are persistent now — so
  every renderer remount tore down and respawned the server. Reuse a live
  stream (scrcpyVideoRegistry.has) so remounts reconnect, matching iOS. The
  device-mismatch check still runs first, so device switching is unaffected.
