Include albumartist in filename; remove Claude API from LLM chain

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.
