8a5b58a817 fix: address code review findings
- Fix artist-ID namespace mismatch in MusicBrainz provider: SyncArtistDiscography
  now stores the canonical Navidrome artist ID (artist_settings.id) as
  external_releases.artist_id instead of the MusicBrainz MBID. Previously the
  MBID was stored, which violated the FK to artist_settings and broke the
  scanner join (local_albums.artist_id is the Navidrome ID), causing every
  external release to be falsely reported as missing and the sync insert to
  fail at runtime. getArtistFilterOptions now also resolves by the Navidrome ID.
- Resolve threshold in FindMissingReleases so the exported primitive honors the
  same zero-means-default contract as ScanArtist/ScanAll.
- Remove dead maxLen==0 guard in scanner.Similarity.
- Inline trivial buildPath helper; drop unused url import in client.go.
- Replace hand-rolled itoa with strconv.Itoa in tests.
- Rewrite SyncArtistDiscography tests to seed artist_settings with the Navidrome
  ID (tests previously seeded the MBID to mask the FK mismatch).
- Fix TestFuzzySmoke to exercise the real dependency (fuzzy.LevenshteinDistance /
  scanner.Similarity) instead of an unused API.
- Fix TestAppRun_ScanLogsMissingReleases to run the scan against a live context
  and assert the missing release is found.
- Document cached_at column in Specification.md and note startup scan / required
  musicbrainz.user_agent in README.
- Stop tracking .serena/ tooling config; add it to .gitignore.

a5911c257c fix: address code review findings
Remove dead code: duplicate ExternalRelease/Artist/ParsedArtist structs in
model.go, ParseArtist/mbArtist/mbArtistData in client.go, ArtistTypeFilter
and related filtering functions in api.go, SyncArtistDiscographyWithFilter
in sync.go, and CacheStats/IsArtistCacheValid in cache.go.

Fix bugs: SaveExternalRelease now stores NULL instead of empty string for
zero CachedAt; sync upserts are now transactional with stale release cleanup;
getCachedReleases returns int instead of *CacheStats; doGet uses url.Values
for proper query encoding of MBID.

Fix tests: removed duplicate TestRun_GracefulShutdown, removed dead code
(_ = dbPath) from TestNewApp, fixed assertions in httptest handler goroutine
to avoid data race, increased rate limiter timing tolerance, removed
Client.Close() calls (no-op removed), fixed sync test cache expiry to use
UPDATE instead of 0 TTL races.

Fix formatting: cancel()}() formatting in main.go, error format string in sync.go.

b0f69d3a4f feat: implement rate limiting and caching layer for MusicBrainz provider
- Add golang.org/x/time/rate dependency for token-bucket rate limiting
- Replace custom channel-based rate limiter with rate.NewLimiter(1, 1)
- Add context.Context support to doGet for cancellation
- Add cached_at column to external_releases via migration 005
- Implement cache hit/miss queries with TTL-based filtering
- Add CacheStats type for tracking cached RGIDs
- Update ExternalRelease struct with CachedAt field
- Add rate limiting tests (1 req/sec enforcement, burst behavior)
- Add cache tests (hit, miss, expired, mixed, empty artist)
- Update migration count test for new migration

674daed93b feat: create MusicBrainz client and data models
Add internal/musicbrainz/ package with:
- client.go: MusicBrainzClient struct wrapping net/http.Client with
  channel-based rate limiter (1 req/sec), doGet method with proper
  User-Agent header, and Close for cleanup
- model.go: ReleaseGroup, Artist, ExternalRelease, and Parsed* structs
- XML parsing functions for release-group list and artist responses
- Comprehensive tests: XML parsing (success, empty, malformed),
  client constructor, doGet (success, non-200, unreachable server),
  rate limiter behavior
