Subject: [PATCH] feat: radio mode uses getSimilarSongs2 for artist/genre-aware
 playback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces getRandomSongs with getSimilarSongs2 seeded from the current track.
Falls back to random if Navidrome returns nothing (no Last.fm config or unknown song).
Deduplicates against songs already in the queue.
Compatible with AudioMuse-AI plugin if added later — same endpoint, better results.
