* fix(web): keep Remote Web loading over plain HTTP without crypto.randomUUID

Browsers hide crypto.randomUUID outside secure contexts, so Remote Web over
http://<lan-or-tailnet-ip> threw while importing the store and never painted.
createAgentStatusAuthorityId now takes its UUID source (renderer passes
createBrowserUuid, main passes node:crypto randomUUID), and the other
unguarded renderer calls go through createBrowserUuid.

* refactor(renderer): route remaining randomUUID fallbacks through createBrowserUuid

Replaces five hand-rolled crypto?.randomUUID?.() fallbacks (including a copy
of the browser-uuid fallback in mint-stable-pane-id) with createBrowserUuid,
and adds an oxlint no-restricted-properties rule so renderer code cannot call
randomUUID directly again.

* refactor(shared): move the non-secure-context UUID generator into src/shared

The white screen came from src/shared, so the fix belongs there. src/shared had
three hand-rolled copies of the same randomUUID-then-getRandomValues-then-Math.random
ladder (nested-repo-telemetry, project-groups, setup-agent-sequencing) because there
was nothing in that layer to import; createBrowserUuid lived one directory over in
the renderer.

createNonSecureContextUuid() now holds the single implementation, @/lib/browser-uuid
re-exports it under the renderer's existing name so no renderer import site changes,
and the three duplicates call it.

That also lets createAgentStatusAuthorityId go back to one argument. The injected
randomUuid source was justified as keeping browser APIs out of shared code, but this
generator is runtime-agnostic — it works unchanged in Node. Injecting it bought no
layering and made the safe choice a parameter every future caller had to get right,
unguarded: a caller could pass () => globalThis.crypto.randomUUID() and restore the
white screen with lint and tests green.

* fix(lint): ban crypto.randomUUID in src/shared and scope the escape hatch

vite.web.config.ts compiles src/shared straight into the web bundle, but the new
randomUUID ban only covered src/renderer/src — so the exact module that white-screened
the app sat outside the guard it shipped with, and the regression could come back with
a green lint. The override now covers src/shared/**/*.ts too; it costs zero diagnostics
because the duplicates it would have flagged are gone. `import { randomUUID } from
'node:crypto'` is untouched, so main-only shared modules keep working.

Both blanket "off" overrides are gone. no-restricted-properties is keyed by property
name, so the moment a second property joins the renderer block those overrides would
have silently exempted it — in the one file that is the escape hatch, and in every test
in the repo. Tests are where people copy patterns from, so they stay covered; the four
real uses carry line-scoped disables with a reason.

* fix(terminal): keep render-desync capture ids inside main's 120-char cap

createCaptureId builds `${Date.now()}-${panePart}-${nonce}`. A real paneKey is
`${tabId}:${leafId}` — two UUIDs, 73 chars after sanitizing — so with a 36-char UUID
nonce the id is 124 chars and main rejects it with 'Invalid render-desync capture id'.
persistHealedReference swallows that into console.error, so it shows up as diagnostics
that silently never appear.

This was already broken on the desktop app, where randomUUID is available; routing the
non-secure path through the same generator would have made it unconditional, including
on the plain-HTTP web client this branch exists to repair.

Bound the pane part rather than the nonce: keep the trailing 40 chars, which is the
whole leaf id (the identifying half, unique on its own) and drop the tab-id prefix, so
ids stay unique and traceable at 91 chars. The 120-char contract now lives in
src/shared next to the IPC args, imported by both sides, so the renderer cannot mint an
id main will reject without the test noticing.

* test(web): cover the whole store graph and the Vault token without randomUUID

The reported stack was the store chunk, not two named modules, so the repro test now
evaluates the store root under the stubbed non-secure crypto. Any new import-time
secure-context call anywhere in that graph fails here, not just the one this branch
removed.

Also ports the request-token regression from #20465, the one piece of coverage the
competing branches for this bug contributed that this one lacked. Both cases fail with
"randomUUID is not a function" when their production change is reverted.

* test(web): restore the real crypto.randomUUID after the non-secure Vault case

randomUUID lives on Crypto.prototype, so stubbing it as an own property of
globalThis.crypto left the restore branch with an undefined descriptor and a
leaked own `randomUUID: undefined`. Swap the whole crypto own property instead,
through one shared stub the repro suite already needed.
