Subject: [PATCH] feat: Add SHAREit-style Home screen and H264 sender
Add unified HomeActivity with Send and Receive buttons.
Implement SenderActivity, ScreenCaptureService with MediaProjection and
H.264 MediaCodec encoder (720p 3 Mbps 30fps), and LibreCastClient.
Integrate ZXing QR scanning for target address input.
