Filename schema now: TT - AlbumArtist - TrackArtist - Title when albumartist
differs from track artist (e.g. pianist vs. composer). Identical artist → old
two-part format unchanged.
metadata_resolver: removed Claude API fallback entirely from _claude_resolve.
Chain is now Ollama (local, free) → OpenRouter (DeepSeek V3, cheap) only.
music_enricher: updated status line and use_claude flag accordingly.

AI-powered per-album pipeline: scan → local hints → MusicBrainz/Discogs/Claude
resolve → cover art → interactive or auto review → tag write + rename + report.
All external dependencies optional; 17/17 unit tests passing.
