fix(updates): remove automatic update nags

[figassis]

Summary

• Remove automatic Jean update dialogs and host-update toasts; keep passive title-bar badges and manual update controls.
• Keep automatic backend CLI updates silent, including failures, while preserving failure badges and explicit installer feedback.
• Remove Agent Browser update offers and stale Web Access reload warnings.

Verification

• 413 frontend suites / 2881 tests passed with two workers; focused silent-update regressions passed.
• Playwright startup/reload tests for desktop and headless hosts, including explicit update feedback.
• agent-browser desktop/mobile visual checks with mocked update availability.
• Typecheck and lint passed. Docker Rust format/Clippy passed; 1339 Rust tests passed, one ignored.
• Final jean:dev image built and isolated runtime served HTTP 200.
• A worktree-modal test timed out under concurrent build load, then passed in isolation and the reduced-worker full run.

Manual smoke test

1. Open Jean Web with outdated Jean/CLI versions and reload. Only passive update badges should appear.
2. Navigate away and return. No update dialog or update toast should interrupt the page.
3. Click an update badge or manually update from Settings. Requested operations should still show progress and results.

Summary by CodeRabbit

• New Features
  • Update availability is now shown passively, without interrupting workflows with update dialogs or notifications. Users can apply available updates on request.
• Bug Fixes
  • Background CLI updates no longer show success or error notifications; failed updates can be retried.
  • Web client version mismatches no longer trigger reload prompts.

Walkthrough

Update availability now uses passive notices instead of availability modals and toasts in several update flows. The Agent Browser update prompt was removed. Background CLI updates and stale web-client checks no longer display update notices.

Changes

Update Notice Behavior

Layer / File(s)	Summary
Record and expose pending updates src/App.tsx, src/hooks/useMainWindowEventListeners.ts, src/hooks/useServerUpdateCheck.ts, src/hooks/useServerUpdateCheck.test.tsx, src/components/layout/MainWindow.tsx, src/components/layout/UpdateAvailableModal.tsx, e2e/tests/update-nags.spec.ts, .ai/todo.md, .ai/lessons.md	Native and desktop updates are recorded as pending versions. Server updates retain pending details without availability toasts or actions. The update modal and its rendering path are removed. Tests check passive notices and applying updates. The notes record the completed checklist, verification results, and base-refresh lesson.
Remove the Agent Browser update prompt src/App.tsx, src/hooks/useAgentBrowserUpdateCheck.ts, src/hooks/useAgentBrowserUpdateCheck.test.tsx	The startup hook and its tests are removed. The hook previously checked for updates after a delay and offered update or defer actions.
Run background CLI updates without notices src/hooks/useCliVersionCheck.ts, src/hooks/useCliVersionCheck.test.tsx	Background CLI updates no longer show toasts or open update UI. Success invalidates CLI queries and dismisses the update notice. Failures are logged, with some failures allowing retry. Tests cover success and rejection cases.
Detect stale web clients without a warning toast src/lib/web-client-version.ts, src/lib/web-client-version.test.ts	The stale-client check still logs and returns true for a differing server build ID, but no longer displays a reload toast. Tests cover differing, matching, and missing build IDs.

Merge Risk: 🟡 Moderate · up to bde64

Update prompts are now passive badges. However, when the desktop app is connected to a remote desktop host, the host and local app updates can share one badge. Clicking it could install a different update than the one shown. This should be confirmed or fixed before merging.

Keep remote desktop-host updates separate from native-shell updates.

If a native client has a local update pending while connected to a remote desktop host, this branch can replace the local pendingUpdateVersion with the host version. src/App.tsx retains the local pendingUpdateRef, so install-pending-update can then install the local package while the badge advertises the host version. If the local update is ready, this guard drops the host update instead. Store the host update separately and route its install action to applyServerUpdate.
