Bare name queries (typing 'metallica') now resolve to an artist MBID via
the fuzzy search added in the previous commit, then BROWSE that artist's
release-groups and recordings instead of text-searching release/recording
titles. That's the only way to fix the core garbage-results issue: MB
indexes release/recording titles, not artist names, so 'recording:metallica'
matches random tracks literally titled 'Metallica' (all scoring 100).
Structure:
- `_split_structured_query` — detects 'Artist - Title' / 'Artist – Title' /
'Artist — Title' shapes. When present, text-search is correct (user
gave an explicit title to match).
- `_resolve_top_artist` — memoized per-instance lookup for the top-scoring
artist MBID. Backend fires artists/albums/tracks searches in parallel
against one shared client instance, and albums+tracks both need the
same artist lookup. Cache + lock means one HTTP call instead of three.
- `_release_group_to_album` / `_recording_to_track` — shared projection
helpers between the browse and text paths so both paths return the
same dataclass shape.
Search flow per kind:
- `search_albums('metallica')` → resolve top artist → browse release-groups
with `type=album|ep|single|compilation` → sort by type priority then
release date desc → Album dataclasses for top N.
- `search_tracks('metallica')` → resolve top artist → browse recordings
with `inc=releases+artist-credits` → dedupe by normalized title (MB
has many live/compilation variants of the same song) → sort by release
date desc → Track dataclasses for top N.
- `search_albums('foo - bar')` → structured query → text-search path
(unchanged behavior, now score-filtered to 80+).
- `search_tracks('foo - bar')` → same.
- Both text-search paths also dedupe through `_search_albums_text` /
`_search_tracks_text` helpers, which apply the 80-score filter that
the artist-first path gets free from the resolver's threshold.
Also dedupes text-path tracks through the new `_recording_to_track`
helper, replacing ~60 lines of inline projection code. Net change is
more lines overall (browse + helpers) but the text paths shrank and
the garbage-results issue is fixed.
