7b7721f002* 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

This folder abstracts metadata lookup into "agents". Each agent can be implemented to get as much info as the external source provides, by using a granular set of interfaces (see interfaces).
A new agent must comply with these simple implementation rules:
- Implement the
AgentName()method. It just returns the name of the agent for logging purposes. - Implement one or more of the
*Retriever()interfaces. That's where the agent's logic resides. - Register itself (in its
init()function).
For an agent to be used it needs to be listed in the Agents config option (default is "deezer,lastfm"). The order dictates the priority of the agents
For a simple Agent example, look at the local_agent agent source code.
