Source worktree pickers from dashboard model

[TraderSamwise]

Summary

• render the dashboard worktree list overlay from service-backed dashboard worktree groups
• build dashboard migrate picker choices from the same dashboard model instead of local worktree enumeration
• add focused tests that fail if dashboard mode falls back to local worktree reads

Verification

• yarn vitest src/tui/screens/overlay-renderers.test.ts src/multiplexer/navigation.test.ts
• yarn typecheck
• yarn lint
• yarn build
• yarn vitest
• pre-push hook: yarn typecheck && yarn lint && yarn test

Release Notes

• Improvements

  • Optimized worktree selection and migration operations to use dashboard-cached data when available, reducing redundant data fetching in dashboard mode.

• Tests

  • Added comprehensive test coverage for worktree picker and list overlay functionality in dashboard context.

📝 Walkthrough

Walkthrough

Two functions — showMigratePicker in navigation.ts and buildWorktreeListOverlayOutput in overlay-renderers.ts — are updated to prefer dashboardWorktreeGroupsCache when in dashboard mode instead of unconditionally calling live worktree service functions. Both changes include new Vitest tests that assert cache-driven behavior and confirm live fallbacks are not invoked.

Changes

Dashboard cache preferred over live worktree lookups

Layer / File(s)	Summary
showMigratePicker cache-first population src/multiplexer/navigation.ts, src/multiplexer/navigation.test.ts	showMigratePicker conditionally builds migratePickerWorktrees from dashboardWorktreeGroupsCache (normalizing (main) entries, mapping to { name, path }, and deduplicating by path) when in dashboard mode; otherwise falls back to listWorktrees/findMainRepo. Tests verify the cache path produces correct picker entries and assert that listWorktrees and findMainRepo are not called.
buildWorktreeListOverlayOutput cache-first population src/tui/screens/overlay-renderers.ts, src/tui/screens/overlay-renderers.test.ts	buildWorktreeListOverlayOutput derives its worktree list from dashboardWorktreeGroupsCache in dashboard mode; the element type now allows path to be optional, and (main) marking changes from a first-index rule to a path-aware condition. Tests verify cache-driven rendering and that listAllWorktrees is not invoked.

Poem

🐇 Hop, hop, no more live calls to make,
The cache holds the worktrees — just go and take!
(main) by path, not by index alone,
De-duped and normalized, cleanly shown.
The tests stand guard so no service is stirred,
A rabbit's best trick: skip what's not preferred! 🌿

In `@src/multiplexer/navigation.test.ts`:
- Around line 3-13: The test is mocking and asserting the wrong dependency for
the fallback behavior. The code now uses listAllWorktrees() as the fallback in
dashboard mode, but the test still mocks listWorktrees. Replace the
listWorktrees mock with a listAllWorktrees mock that throws an error with
message indicating that the worktree function should not run, ensuring the test
properly verifies that the fallback uses listAllWorktrees() and maintains the
regression guard against calling local worktree functions in dashboard mode.
