26 new unit tests in tests/test_musicbrainz_search.py covering:
- Cover Art URL construction (release + release-group scope, empty MBID,
unknown scope fallback)
- Structured query splitting (hyphen, en-dash, em-dash, bare name, no
false-positive splits on hyphens-inside-words)
- Artist search: score filtering, strict=False call contract, exception
handling, genre extraction from MB tags, mbid/name validation
- Top-artist resolver: memoization by normalized query, sub-threshold
returns None, negative-result caching, empty-query short-circuit
- Album search routing: bare query → browse path, structured query →
text path, no-artist-match falls back to text, text path score filter
- Track search routing: browse path, dedupe-by-title across
live/compilation variants, structured query → text path, text path
score filter
All mock the underlying MusicBrainzClient — no network calls.
Also adds a WHATS_NEW entry under 2.40 explaining the three user-visible
changes: Artists section now populates, album/track results match the
searched artist instead of random title collisions, and search completes
in ~3 seconds instead of 30+.
