Two torrent-path robustness fixes surfaced while testing WebTorrent peering:
- streamVideo now sets announce: [...WSS_TRACKERS]. A .torrent-buffer add (Blossom companion piece-map) has an EMPTY embedded announce list, so without this it reached no tracker, found no WebRTC peers, and streamed webseed-only (looked like a stuck '1 peer'). WebTorrent merges these with any trackers already on the source.
- A forced-torrent playback now falls back to the hosted URL when the torrent DEFINITIVELY fails (e.g. a transient companion-lookup failure under relay congestion, or a dead swarm) instead of hard-erroring 'No playable source found'. Only triggers on real failure, not a slow swarm. Rollback noted inline.
