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.
