Deluan Quintão bd9fa1c602 feat(listenbrainz): match collaboration top-songs via all credited artist MBIDs (#5670) ... * refactor(agents): drop single Artist fields from Song, keep only Artists Song now represents credited artists solely via the Artists slice; the single Artist/ArtistMBID fields and the ArtistList passthrough are removed. Equals continues to hash the whole value. * refactor(lastfm,listenbrainz): build Song.Artists in built-in agents Last.fm and ListenBrainz now populate the Artists slice directly. For ListenBrainz top songs, all credited artist MBIDs are mapped (the combined display name on the first credit plus MBID-only collaborators) instead of keeping only the first MBID, feeding the matcher's per-MBID specificity. * refactor(external): set Song.Artists in top-songs enrichment getMatchingTopSongs now seeds an Artists entry from the known artist when a song carries none, replacing the single Artist/ArtistMBID writes. * refactor(plugins): fold single-artist SongRef into Song.Artists SongRef keeps its single Artist/ArtistMBID fields as part of the plugin wire contract; songRefToAgentSong now folds them into a one-element Artists list when a plugin sends no artists array. * refactor(matcher): read Song.Artists directly groupQueries consumes s.Artists now that ArtistList is gone; test inputs build the Artists slice. * fix(matcher): keep MBID-only artists as identity signals Review follow-up: an artist credited only by MBID (empty ID and name) was dropped before resolution in four places, defeating the multi-MBID matching path this PR adds. - matcher.groupQueries: treat a non-empty MBID as a usable artist signal - external.getMatchingTopSongs: backfill the primary credit's name/MBID when the agent left them empty - plugins.songRefToAgentSong: fold a single-artist SongRef when only ArtistMBID is set (not just when Artist name is set) - listenbrainz.topSongArtists: return nil instead of an empty-name placeholder when neither name nor MBIDs are present * fix(external): only backfill top-song artist onto an unnamed credit Review follow-up (codex P2): the previous backfill stamped the queried artist's MBID onto Artists[0] whenever it was empty, even when that credit already named a different (e.g. featured) artist — producing a mismatched name+MBID pair that could mis-rank matches. Now only an unnamed first credit is filled (it is, by construction, the queried artist); an already-named credit is left untouched.
