Split the monolithic IbusEsp32 class into composable layers: - KLineTransport: UART, GPIO ISR, ring buffers, idle detection - IbusHandler: BMW I/K-Bus FSM, source filtering, packet callback - IbusEsp32: thin facade preserving the original API Library renamed from IbusEsp32 to AutoWire. Existing sniffer sketch (main.cpp) requires zero changes. All 3 ESP32 environments build cleanly (esp32dev, esp32-c3, esp32-s3).
