rusqlite 0.40 removed ToSql/FromSql for u64 (SQLite integers are i64):
every u64 column now reads/writes through an explicit i64 cast. It also
rejects a multi-statement execute() instead of silently running only the
first statement — which is what catalog.rs's editions/logical_albums
prune had been doing all along; it is an execute_batch now, so the
logical_albums prune finally runs.

New frontend-agnostic crate qbz-external-reco: blends Last.fm + ListenBrainz
recommendation signals into the Discover "External Recommendations" carousels,
validating every candidate against the Qobuz catalog (ISRC direct -> MusicBrainz
inc=isrcs bridge -> fuzzy text scorer, gated) before display. Four carousels
(C1 similar artists / C2 similar tracks you haven't heard, C3 listened-but-not-
recently, C4 deep cuts from known artists) capped at 20 with daily rotation over
a larger cache-backed pool, plus a Qobuz-editorial cold-start fallback (top
albums + artists) when no external source is connected. Round-robin blend across
sources. Resolution cache (per-user SQLite, 30d hits / 7d misses, WAL).
Supporting public read methods added to qbz-integrations:
- Last.fm: get_top_artists / get_top_tracks / get_loved_tracks /
get_recent_tracks / get_similar_tracks (public reads via the Cloudflare proxy).
- ListenBrainz: get_cf_recommendations / get_recent_listens /
get_metadata_recordings (204/404 -> empty, never error).
- MusicBrainz: get_recording_isrcs (the MBID -> ISRC bridge).
Engine is headless and unit-tested (matching + cache); no qbz-ui dependency.
