Each search now logs:
- Phase 0 (index): FTS5 query time + hit count
- Phase 1 (MB): per-entity elapsed + cache hit detection + total wall time
- Phase 2-3 (rerank): whether index was used, elapsed
- Total: breakdown of all phases
Also adds a 4s context.WithTimeout on the MusicBrainz API calls so
a slow MB server degrades to index-only results rather than blocking
indefinitely.
