Drops the custom WebRTC DataChannel pipeline + pion deps + WSS signaling client + wire framing. Every in-browser playback now uses HLS over HTTP from the daemon (Tailscale/LAN/UPnP). Browser P2P never re-enabled. Wire renames (incompatible with web < 2026-05-26): agent.WebRTCSession => agent.StreamSession, SyncResponse.WebRTCSessions (JSON: webrtcSessions) => StreamSessions (JSON: streamSessions). MIN_AGENT_VERSION is bumped to 0.9.4 on the web side so older agents see an upgrade card. Also fixes the libx264 'VBV bitrate > level limit' abort by clamping the encoder bitrate to the effective output height instead of the requested label (carried over from the prior 0.9.3 unreleased work). The seed_file vertical (mode=seed_file handler + engine.SeedFile) was retired with the in-browser P2P player. [downloads.webrtc] config block deleted; existing TOML files with the section still parse fine.
