- Fix FK constraint violation in SyncArtistDiscography: delete
notifications_sent rows before external_releases to prevent
constraint failure when re-syncing artists with prior notifications.
- Implement per-artist type filtering: FilterReleaseGroups now accepts
FilterOptions with IgnoreSingles/IgnoreCompilations flags, read from
artist_settings table via getArtistFilterOptions.
- Fix inconsistent error wrapping: GetExternalRelease now wraps errors
with fmt.Errorf like all other functions in the package; updated test
to use errors.Is for sql.ErrNoRows check.
- Add tests: FilterReleaseGroups ignore singles/compilations,
SyncArtistDiscography per-artist type filtering, and FK-safe resync.
