Implement HFP client (Hands-Free Unit role) for the ESP32 test harness: Firmware: - bt_hfp.c/h: Full HFP client with call control, audio, volume, DTMF, voice recognition - Enable HFP in sdkconfig.defaults with Wide Band Speech support - Add HFP commands/events to protocol.h and cmd_dispatcher.c Python MCP tools: - 15 new tools: enable, connect, audio_connect, answer, reject, dial, send_dtmf, volume, voice_recognition_start/stop, query_calls, status - Full protocol constants in protocol.py Tested: HFP enable returns role='hands_free_unit', ready for AG pairing
