- Added embedded-hal 1.0 as direct dep (already transitive via embedded-hal-async) - SimpleLed<P: OutputPin> now generic over any HAL — single definition in driver/ - Removed duplicate SimpleLed from board/esp32s3.rs and board/wio_tracker_l1.rs - Changed BoardParts.led from Option<L> to L — boards with no LED use () - Display task calls led.set_rgb() unconditionally (no-op for () boards) - RAK board: led: () instead of led: None
