feat: add Android USB serial port support via USB Host API

- Add USB Host permissions and device filter to AndroidManifest.xml - Create UsbSerialPlugin Kotlin plugin for USB Host API (enumerate, permission, open devices) - Add serial_connect_fd command for Android to accept USB file descriptors - Create RawFdStream wrapper for async I/O on raw file descriptors - Make run_serial_with_poll generic over AsyncRead+AsyncWrite - Register UsbSerialPlugin in MainActivity
chore: add Android debug keystore for APK signing
