The reco_store/commands.rs module no longer hosts any registered Tauri
commands. Its surviving content is purely helper logic consumed by V2
home recommendations in commands_v2/library.rs.
- Rename reco_store/commands.rs -> reco_store/helpers.rs
- Drop the unregistered/uncalled #[tauri::command] entries
(reco_log_event, reco_train_scores, get_playlist_suggestions,
reco_backfill_genres, reco_needs_genre_backfill) and their dead
scoring helpers (build_scores, build_track_entries, decay_factor,
current_timestamp, etc.) along with RecoTrainStats / RecoScoreCounts
/ BackfillStats structs that only those commands referenced.
- Update commands_v2/library.rs to import from
crate::reco_store::helpers::* (still uses get_home_seeds_internal,
resolve_albums, resolve_tracks, resolve_artists, album_to_card_meta).
