- Frontend was concatenating Track and Artist inputs into a single
query string, causing Spotify to return mixed results matching
either word in any field. Now sends track and artist as separate
params; backend builds field-filtered query (track:X artist:Y).
- Result limit was silently capped at 10 in spotify_client.search_tracks
via min(limit, 10). Raised to respect requested limit up to
Spotify's API max of 50.
- iTunes fallback endpoint updated with same field-specific params.
- Legacy ?query= param still supported for backward compatibility.
