feat(palette): full-text search over conversation event logs

[Tryanks]

Implements #122. The ⌘K palette matched session titles only; content was unsearchable.

• Index: lazy, in-memory, in tcode-services over the existing per-session JSONL. Each cached session is fingerprinted by file length + mtime; queries reparse only changed sessions. No SQLite (no existing dep), no watcher threads — freshness checks ride the query.
• Extraction: pure extract_searchable_entries folds StoredEvents through the timeline (no duplicate streaming deltas), covering user/assistant/steering messages, attachment paths, commands, changed files, tool names/inputs, subagent summaries, web searches.
• Palette: a localized Messages group appears after a 150 ms debounce; parsing/search run on the background executor. Selecting a hit opens the session with a one-shot turn target — the chat list leaves tail-follow, scrolls to the turn, and highlights it (works for the already-active session too).
• Latency (estimated): cold ~100–300 ms for ~200 sessions (20–40 MB JSONL), warm ~5–20 ms.
• Tests: extraction (user/assistant/tool events), matching + snippet bounds, and a persisted-fixture query→(session, turn) integration test.

Gates: fmt / clippy -D warnings / full workspace tests — green locally.
