Implement UDS Service 0x22 (Read Data By Identifier) with support for: - Engine ECU (0x7E0): boost pressure, fuel rail pressure, lambda, torque, wastegate position, ignition timing, knock correction per cylinder - DSG Transmission (0x7E1): current gear, selector position, oil temp - Instrument Cluster (0x714): RPM, ambient light sensor Also adds ECU_EMULATOR_SPEC.md with full protocol documentation.
