Add 5 universal communication modules: speak ANY protocol and system

- Universal Proto: HTTP/REST, gRPC, WebSocket, MQTT, CoAP, raw sockets - any protocol auto-detected - IoT Swarm: smart home control via MQTT, CoAP, Zigbee, Z-Wave, Thread, LoRa - Industrial SCADA: Modbus TCP/RTU, Profibus, OPC-UA, EtherCAT for PLC and factory automation control - Vehicle Comm: OBD-II, UDS, KWP2000, CAN-FD for vehicle diagnostics and ECU reprogramming - Message Forge: craft & parse any message format (HEX, JSON, Protobuf, binary, XML) with payload injection Brings toolkit to 42 modules. Cardputer can now communicate with virtually any device or system.
