Wires anacrolix/torrent's built-in webtorrent package so a browser running webtorrent.js can fetch pieces from this CLI via WebRTC data channels. The daemon stays the seeder; we never relay bytes through TorrentClaw infrastructure — same legal posture as today. Changes: - internal/config: new [downloads.webrtc] section (enabled/trackers/stun_servers/turn_servers/turn_user/turn_pass). Disabled by default, opt-in via config.toml. When enabled but trackers / STUN slices are empty, defaults are reapplied on Load() so users get a working setup with a single `enabled = true`. - internal/engine: TorrentConfig gains WebRTCEnabled / WebRTCTrackers / ICEServers; NewTorrentDownloader populates ClientConfig.ICEServerList and forces NoUpload=false when WebRTC is on (browsers can't pull otherwise). buildMagnet now accepts variadic extra trackers and the downloader method prepends WSS trackers so anacrolix's webtorrent.TrackerClient picks them up first. - internal/engine/webrtc.go: BuildICEServers helper converts the TOML WebRTCConfig into []webrtc.ICEServer with shared TURN credentials. - internal/cmd/daemon.go + download.go: pass WebRTC config through to the engine. Tests (8 new, all green; full suite 0 lint issues, 0 vet): - buildMagnet free function: defaults-only, with extras, trim+empty-skip - downloader method: WebRTC disabled keeps WSS out, enabled prepends them - BuildICEServers: nil when disabled, STUN-only path, TURN+credentials - NewTorrentDownloader: full WebRTC-enabled construction (logs WebRTC peer enabled, magnet contains wss://tracker.torrentclaw.com) End-to-end smoke (browser ↔ unarr peer transfer) is deferred to a manual test once tracker.torrentclaw.com WSS is live.
