* feat(library): effective genre falls back to MusicBrainz enrichment
Converted packs rarely carry a genres manifest key — on Byron's real
library 1188/1190 songs had no genre, starving the genre facet and the
career passport rack (2 usable genres) while song_enrichment already
held MB genres for 636 matched songs.
The effective-genre expression now resolves: per-song override → pack
genre → json_extract(enrichment.genres, '$[0]') for MATCHED rows only
(review/failed candidates could carry the wrong recording's genres).
Same fast-path gating as before: the plain indexed column is used
unless overrides or enrichment genres actually exist; stand-in DBs
without the table degrade via the OperationalError guard. Career
passports pick this up automatically through _effective_genre_expr().
