Add OBD-II K-line support (ISO 9141/14230) with scanner example
New protocol handler alongside BMW I/K-Bus:
- KLineObd2: 5-baud slow init, fast init (TiniPulse), request/response
with half-duplex echo clearing, PID convenience wrapper
- Obd2Pids.h: ~20 common PIDs with SAE J1979 decode helpers
- obd2_scanner.cpp: polls RPM, speed, coolant, throttle, voltage
Build config changes:
- config.h: KLINE_* defaults (10400/8N1/MOD256/no idle detect)
- platformio.ini: build_src_filter separates sketches, new
[env:obd2-scanner] environment with KLINE_TX_INVERT=0
