Rename library from AutoWire to K-Line

Library dir: lib/AutoWire/ -> lib/KLine/
Site title, docs, CLAUDE.md, platformio.ini all updated.
All 4 firmware environments build clean.

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

Refactor: extract KLineTransport and IbusHandler from IbusEsp32

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).
