Replace the directory-scan queue with a real ingestion pipeline: provider -> fetcher -> cache -> ready queue, driven by a background prefetch thread. - subsonic.py: minimal OpenSubsonic client (salted-token auth, getPlaylists/getPlaylist, raw streaming download). - providers/navidrome.py: pick tracks from a playlist (by name or id), with anti-repeat and periodic playlist reload. - fetchers/subsonic.py: atomic download into the shared cache. - db.py: SQLite state — append-only play history (anti-repeat + stats) and cache_files LRU retention (keep the N most recently played). - queue.py: prefetch buffer + retention on play; graceful degradation to the stream's local-cache fallback when no source is configured. - api.py: GET /next now carries real title/artist metadata. - Config via .env (Navidrome credentials), persistent state/ volume, httpx dependency. Verified end-to-end against a live Navidrome: playlist resolved, tracks downloaded and broadcast, retention and history correct. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
