Add search to new-thread project picker

[colonelpanic8]

Summary

• replace the new-thread project menu with a searchable picker
• narrow candidates incrementally by project name or workspace path as the user types
• auto-highlight the first remaining candidate so Enter selects it
• preserve the existing New project action

Verification

• vp test run src/components/chat/draftHeroProjectSearch.test.ts --project unit
• vp lint and vp fmt on the changed files
• pnpm run typecheck in apps/web

Isolated exact-head browser verification of incremental search completed against disposable projects; the server and test data were stopped and removed afterward.

Exact-head evidence

Revalidated at 064fa4b on current main (9a0a071): focused tests, vp check, and vp run typecheck passed. The capture uses only disposable local projects.

Note

Low Risk
UI-only change to draft hero project selection with tested helpers; no auth, data, or API impact.

Overview
Replaces the draft-hero project menu with a searchable Combobox so users can filter projects by title and workspace path (multi-token matching) while keeping sidebar sort order.

Filtering and picker behavior live in new draftHeroProjectSearch helpers: prefixed item values keep projects distinct from the New project action, filteredItems always include that footer action, and autoHighlight supports Enter on the first match. Keyboard handling blocks accidental Enter on New project after a failed search until arrow navigation, and preserves IME composition on Enter.

Unit tests cover filtering, item lists, and key-resolution edge cases.

Note

Add search to the new-thread project picker

• Replaces the menu-based project selector in DraftHeroHeadline with a searchable Combobox that filters projects by title and workspace path using multi-token matching.
• A "New project" action item is always appended at the end of the picker list; selecting it opens the add-project command palette.
• Keyboard handling in draftHeroProjectSearch.ts preserves IME Enter composition and requires explicit arrow-key navigation before Enter can select the "New project" footer action after a failed search.
