feat: replace neko with native GStreamer WebRTC for desktop streaming

Replace the neko binary dependency with a native GStreamer pipeline
(ximagesrc -> vp8enc -> webrtcbin) for desktop video streaming. This
removes the external neko process and integrates screen capture directly
via gstreamer-rs crate bindings behind a `desktop-gstreamer` feature flag.

Key changes:
- Add desktop_gstreamer.rs with GStreamer WebRTC pipeline management
- Rewrite signaling protocol (ready/offer/answer/candidate over WS)
- Add leaky queues and videorate for low-latency streaming
- Rewrite ICE candidates to 127.0.0.1 for Docker connectivity
- Constrain UDP port range (30000-30100) via libnice agent
- Update TypeScript SDK desktop-stream.ts for new signaling
- Update inspector DesktopTab with WebRTC Live View
- Update Dockerfiles to install GStreamer dev packages
