LinYushen 23136da34f feat(search): implement full-text search for issues (#507)
* feat(search): implement full-text search for issues

Add pg_bigm-based full-text search across issue titles and descriptions,
with API endpoint, CLI subcommand, and web Cmd+K search dialog.

- Migration 032: pg_bigm extension + GIN indexes on title/description
- Server: GET /api/issues/search?q=... with pagination and total count
- CLI: `multica issue search <query>` with table/json output
- Web: Cmd+K command palette using cmdk, with debounced search

* fix(search): address review feedback on search implementation

1. Escape LIKE special characters (%, _, \) in handler to prevent
   matching anomalies from user input.
2. Wire AbortController signal into searchIssues fetch so in-flight
   requests are actually cancelled on new input.
3. Fix offset=0 falsy check — use !== undefined instead of truthiness.
4. Merge results + count into single query using COUNT(*) OVER()
   window function, eliminating the duplicate DB round-trip.
5. Exclude done/cancelled issues by default; add include_closed
   parameter to API, CLI (--include-closed), and web client.

* fix(search): default web search to include all statuses

Pass include_closed: true in the web Cmd+K search so results include
done and cancelled issues by default, matching the reviewer's request.

* feat(search): add comment search with snippet extraction

Extend search to cover issue comments in addition to title/description.
Results are deduplicated at the issue level, with match_source and
matched_snippet fields indicating where and what matched.

- Migration 033: pg_bigm GIN index on comment.content
- SQL: EXISTS subquery for comment matching, correlated subquery for
  snippet extraction, 3-tier ranking (title > description > comment)
- Server: SearchIssueResponse with match_source and matched_snippet
- Web: show comment icon + snippet below issue title when matched
- CLI: MATCH column shows source and truncated snippet

* feat(search): redesign search dialog to match Linear's spacious style

- Widen dialog from sm (384px) to xl (576px) with top-20% positioning
- Larger search input with icon, generous padding, and ESC hint
- Use cmdk primitives directly for full style control
- Taller result list (400px / 50vh), spacious result items (py-2.5)
- Rounded-lg items with accent highlight on selection
- Cleaner border separator between input and results
