VTech Baby Pro Bridge: reconstructing local camera streaming

VTech Baby Pro Bridge reconstructs local streaming from an RM-series camera through TUTK/Kalay and VTech's X25519 and ChaCha20-Poly1305 layer. Its C bridge serves video through RTSP, WebRTC and HLS, while companion scripts probe the owner's paired Android app for connection values and use SDK libraries extracted from that app.
