Interface: BluetoothSppTransport

Bluetooth SPP (Serial Port Profile, classic Bluetooth).

Verified working on Windows and Linux via the OS-paired RFCOMM device path (the runtime's serial implementation satisfies both serial and bluetooth-spp transport keys). macOS still untested. Baud rate is deliberately absent: SPP negotiates its own framing, and the value on /dev/rfcomm0 is fictional.
