Fixes #1 -- --port mode with wlr-screencopy backend caused panic at negotiate_format() because self.args.output is None and .expect() was called unconditionally. Changes: - Introduce StreamingEncoder enum wrapping EncState (MP4) and SwEncState (WebRTC) with unified frames_rgb/encode_frame/flush API - Add WebRTC fields to State<S> (webrtc, webrtc_tx, webrtc_rx, webrtc_frames_sent) matching Portal backend pattern - State::new() returns Result<Self> for clean WebRtcState init failure - negotiate_format() branches on webrtc_tx: WebRTC path uses SwEncState::new_webrtc(), MP4 path unchanged (hardware VAAPI) - Add poll_webrtc() method to drive signaling + channel drain - Event loop calls poll_webrtc() each iteration - Fix pre-existing test/bench Args construction (Option<String> output, missing no_persist field)
