Add a second playback source and a weighted scheduler mixing it with Navidrome: - Scheduler picks a provider by SOURCE_WEIGHTS, falling through to the others when one has nothing ready, so no source can stall playback. - YtdlpProvider reads a hand-maintained config/urls.txt; container URLs (playlist/album/label/artist) are flat-extracted and one entry is drawn at random, honouring the anti-repeat window. Adds Track.source_url. - YtdlpFetcher downloads bestaudio via the yt-dlp library, reusing the atomic hidden-temp-then-rename pattern; Liquidsoap decodes the result. - Queue now dispatches to a fetcher registry keyed by backend. - Sweep orphaned download temp files on daemon startup (leftovers from a killed container otherwise pile up and trip the stream fallback). Verified end-to-end: yt-dlp opus decoded and served as 192 kbps MP3, and the 3:1 default mix observed in play history. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
