Add MusicLibrary.Collection.Enrichment module with batch scrobble, artist country, and selected release enrichment from existing tables. Wire enrichment into all four collection API endpoints (index, latest, random, on_this_day). New JSON fields: scrobble_count, last_listened_at, artist_country, selected_release. Uses 3 fixed-count batch queries regardless of page size — no N+1 risk. No schema changes or migrations required.
