SongLink can return incorrect track IDs (e.g. a different track from the
same album). Qobuz already had verification via qobuzTrackMatchesRequest.
This adds equivalent verification for Tidal and Deezer using a shared
trackMatchesRequest() helper in title_match_utils.go that checks artist,
title, and duration. Mismatched SongLink/ISRC results are now rejected
so the wrong audio is never embedded with Spotify metadata.
