feat(matcher): match similar/top songs by multiple artists (#5668)
* feat(matcher): add Song.Artists (agents.Artist) and field-wise song dedup

* refactor(matcher): make song equality an agents.Song.Equals method via hashstructure

Move the sameSong free function from core/matcher into an Equals method on
agents.Song, following the model.MediaFile/Album.Equals convention. Uses strict
hashstructure hashing (nil opts, no IgnoreZeroValue) to preserve the original
whole-value equality contract. Tests moved to core/agents.

* feat(matcher): match by multiple artists with overlap ranking and artist-ID fast-path

* refactor(matcher): rank artist overlap and specificity above the preferred-track flag

Identity signals (specificityLevel, artistOverlap) now outrank the taste
signal (preferredMatch) in betterThan. A starred/4-star track that is a worse
identity match no longer beats a more specific or higher-overlap track.
PreferStarred still breaks ties when specificity and overlap are equal.

* fix(matcher): score artist-MBID specificity against all credited artists, not just the last

sanitizedTrack.artistMBID (string) replaced with artistMBIDs (map[string]struct{}) so
bucketTracks collects all credited owned MBIDs per query instead of last-write-wins.
computeSpecificityLevel tests set membership, letting each of a collaboration's
MBID-bearing artists reach the proper specificity level (4/5) independently.

* feat(plugins): carry multiple artists (with IDs) through SongRef conversions

* feat(plugins): regenerate schemas and PDK wrappers for multi-artist SongRef

* refactor(matcher): tidy bucketTracks accumulator and artist resolution

Replace bucketTracks' two parallel per-track maps (overlapByQuery/mbidsByQuery)
with a named queryAccum struct (F2). Collapse resolveArtists' four hand-mutated
parallel maps into a pendingArtist slice with derived nameToQueries/mbidToQueries
maps (F1). Replace the own() method on resolvedArtists with a package-level
addToSet helper that drops the method/receiver indirection (F3).

* docs(matcher): trim comments that restate the code

* fix(plugins): use Vec::is_empty for slice fields in generated Rust PDK

* fix(matcher): treat a resolved artist ID as an identity match for specificity

* docs(matcher): reflect artist-ID identity in the specificity ladder
