feat: add pinned threads and thread ID search

[jordant97]

Summary

• Pinned threads: Right-click any thread → "Pin thread" to pin it to the top of its project's thread list. Persisted to localStorage. Visual pin icon indicator. Unpin via context menu.
• Thread ID search in Command Palette: Pasting a copied thread ID into ⌘K now finds the matching thread (previously only searched by title/branch/project).
• Sidebar filter input: New filter icon next to the Projects header opens an inline search that filters threads by ID or title across all projects, including collapsed ones.

Changed files

• apps/web/src/uiStateStore.ts — pinnedThreadKeys state, pinThread()/unpinThread() actions, persistence & cleanup
• apps/web/src/components/Sidebar.tsx — Pin icon, context menu entries, pinned-first sorting, filter input UI, auto-expand on filter
• apps/web/src/components/CommandPalette.logic.ts — Added thread.id to searchTerms
• apps/web/src/uiStateStore.test.ts — Updated test fixture

Test plan

• Right-click a thread → "Pin thread" → thread moves to top with pin icon
• Right-click pinned thread → "Unpin thread" → returns to normal position
• Pin persists after page reload
• ⌘K → paste a thread ID → thread appears in results
• Click filter icon in sidebar → type thread ID → matching threads shown (even in collapsed projects)
• Press Escape or click filter icon again to dismiss filter
• Existing tests pass (uiStateStore, CommandPalette.logic, threadSort)

Note

Medium Risk
Adds new persisted UI state (pinnedThreadKeys) and modifies sidebar thread ordering/filtering logic, which could affect thread visibility/order and localStorage migrations if buggy.

Overview
Adds pinned threads in the sidebar: threads can be pin/unpinned from the context menu, display a pin indicator, persist via uiStateStore localStorage, and are sorted to the top of each project’s thread list.

Adds a sidebar thread filter UI that filters threads by ID or title (showing all matches without the preview limit), and extends command palette thread search to include thread.id in searchTerms for ID-based lookup.

Note

Add pinned threads and thread ID search to the sidebar

• Threads can be pinned or unpinned via the sidebar context menu; pinned threads appear at the top of each project's thread list and display a pin icon in their row.
• Pin state is persisted to localStorage and restored on load, with cleanup when threads are removed or their UI state is cleared.
• A filter control in the sidebar header lets users search threads by ID or title, with the filter input toggled via a toolbar button.
• Thread IDs are now included in command palette search terms so threads can be found by ID in addition to title, project, and branch.

Approvability

Verdict: Needs human review

This PR introduces two new user-facing features: pinned threads and thread filtering by ID/title. While the implementation is frontend-only and well-scoped, new features introducing new UI workflows and state management warrant human review to ensure the behavior meets product expectations.
