0677271709 fix(orchestration): reap leaked worker terminals via process-incarnation fallback — stops an unbounded PTY/process leak on Remote Server (OOM / cgroup PID exhaustion) (#18790)
* fix(orchestration): remint live handle from process incarnation on worker release

When a durable terminal handle goes stale (rendererGraphEpoch fence),
inspectWorkerTerminal re-mints a live handle via
resolveTerminalHandleByProcessIncarnation + matchesProcessIncarnation so
release/stop/read act on the still-running PTY instead of reporting
missing and leaking the agent process tree.

- keep main shared host-scope re-exports; add matchesProcessIncarnation
- wire observation.terminalHandle through control/stop/release
- rebuild release-completion on main structured paths
- on missing/unattached + provably exited: settleDead fence first, then
  same-incarnation settleWorker fall back (archive may block settleDead
  mid-request); settle before recovery defer

* fix(orchestration): derive SSH host scope from the reminted handle; reuse fresh-request recovery guidance for structured workers

Addresses two open CodeRabbit review comments on PR #18790.

inspectWorkerTerminal read the dispatch authority with the stale durable
terminalHandle, so after a remint the lookup resolved nowhere and
currentHostScope was always undefined — an SSH worker with no liveness
verdict and no persisted host_scope got classified from terminal.connected
instead of unverifiable. It now reads the same effectiveHandle every other
observation in the function uses.

stopStructuredWorkerForRelease told the caller to repeat the release with
the same --retry-request, which only replays the stale release_unknown
receipt and made a structured-worker close failure permanently unretryable.
It now sources releaseUnknownRecovery from worker-release-completion so the
fresh-request-ID guidance lives in one place.

Pre-commit lint-staged (oxlint + oxfmt) run manually: clean.

* test(orchestration): exercise incarnation recovery through runtime paths

* test(orchestration): pin the incarnation read scenario to the reminted terminal

The read scenario only asserted that the call resolved, so it documented
nothing about which handle the read reached. Assert that the handle
readTerminal received resolves to the registered pane and incarnation, so
the scenario proves the read went through the reminted terminal instead of
passing on the incarnation fence's throw.

* refactor(orchestration): drop redundant incarnation prefix check; require liveTerminalHandle

* feat: add freebuff as a first-class TUI agent (#42)

## ELI5

Add Freebuff (`freebuff`) as a recognized first-class TUI coding agent
in Orca alongside Codebuff and other supported agents.

## What Changed

- Registered `freebuff` across shared TUI agent definitions,
configuration catalogs, display names, and telemetry schemas.
- Added agent icons, favicons, status mappings, and mobile asset
references for Freebuff.
- Added localization strings across supported language packs (`en`,
`es`, `fr`, `ja`, `ko`, `zh`) and updated locale translation policy.
- Documented Freebuff CLI in README agent table (`npm i -g freebuff`).

## Why

Freebuff is a CLI coding agent twin of Codebuff (`npm i -g freebuff`).
Adding it to the catalog enables users to launch worktrees, run
automated sessions, and pick Freebuff directly within Orca.

## Linked Issue

N/A

## Visual Proof

`N/A` - Catalog registration and metadata definition for CLI agent
launch; UI rendering uses existing TUI agent picker and status
components.

## Testing

- Verified TypeScript contracts, schemas, and catalog configurations.
- Tested CLI detection / agent picker integration locally on Linux
(`worktree create --agent freebuff`).

## AI Disclosure

Assisted by AI coding tooling.

- [x] I explained what changed and why (including ELI5)
- [x] Before/after screenshots or videos attached for UI changes, or
`N/A` with reason
