thePR0M3TH3ANandClaude Opus 4.8 4e5bfaa6af [playback] harden WebTorrent streaming + add forced-source test deep links
WebTorrent (handleTorrentStream) hardening:
- Resolve only when playback is actually viable (loadeddata/canplay/playing),
  not the instant streamTo() is called. A dead/too-slow swarm is no longer
  reported as success, so the caller's fallback can run.
- Pre-playback torrent errors reject (caller falls back); post-playback errors
  go to an onPlaybackError hook instead of a dead reject().
- Mid-stream stall watchdog surfaces an onStall hook ("waiting for peers").
- Fix a <video> listener leak: stream listeners are tracked and torn down
  before the next stream and on cleanup() (the modal reuses one element).
- Stream the largest decodable file from a multi-file torrent and deselect the
  rest (wider ext set: mp4/m4v/webm/mkv/mov/ogv/ogg) so the swarm isn't spent
  downloading files we never play.
playbackCoordinator wires onStall/onPlaybackError to user-facing status.

Forced-source deep links (test affordance):
- The main app honors ?v=<nevent>&playback=torrent|url (mirrors the embed
  player) to force a playback path; a missing source shows a clear message.
- The video share menu gains "Copy WebTorrent URL" / "Copy CDN URL" items that
  copy the forced-source deep link (disabled with a reason when unavailable).

Tests: webtorrent-handlers (resolve-on-readiness, pre/post-ready errors, stall
fires/clears, largest-file select/deselect, no listener accumulation),
playback-forced-source (param normalization), videoMenuRenderers (copy items +
availability). All mutation-verified.
