ListenBrainz surfaces producers/session players/band members (Max Martin,
Dominic Howard) that co-occur in listens but have no releases of their own —
they showed as bare rows with an empty page. _derive_albums now drops a
surfaced artist (deletes their pending suggestion) when their MB discography
has no core release-group (Album/Single/EP, no secondary type), catching both
empty discographies and soundtrack/production-only credits, while keeping real
singles/EP-only artists. On browse failure the suggestion is kept.
Test fake browser gains default_core so scoring tests keep surfacing candidates.

- Client filters the row's album thumbnails to full albums only (hides
singles/EPs left over from pre-albums-only sweeps).
- Worker: re-deriving an artist deletes its pending album suggestions that are
no longer picks (stale singles / now-owned), keeping wanted/dismissed rows,
so the suggestion set self-cleans instead of accumulating.

_derive_albums now also picks the artist's most-played album (Last.fm,
matched into the browsed discography by MBID then normalized title),
alongside the newest. Same release -> one row tagged newest,popular.
albumReason persisted; run_discovery threads an optional popularity provider.

Discovery's "Suggested albums" surfaced singles and EPs because
_derive_albums filtered with is_core_release (Album/Single/EP). Add a
discovery-only _album_kind_ok gate that, when discover.albumsOnly (new
config, default true), requires primary_type == "Album" with no secondary
types. is_core_release is untouched — the monitor/scan still use it.
Exposed discover.albumsOnly in the discover config route + a Discovery
settings toggle. Worker + web tests added.
