Pull Request Overview

Adds a Matter event callback API and example to the ESP32 Arduino Matter library, enabling users to register for and handle all supported Matter device events.

  • Introduce matterEvent_t enum and matterEventCB type, with onEvent() registration API.
  • Wire up event dis in app_event_cb() and initialize the static callback variable.
  • Provide a complete example sketch and update keywords.txt for editor highlighting.

  • [nitpick] Add a brief Doxygen-style comment explaining the purpose and usage of matterEventCB and the onEvent registration method to improve API discoverability.
  using matterEventCB = std::function<void(matterEvent_t, const chip::DeviceLayer::ChipDeviceEvent*)>;

  • [nitpick] Consider adding unit or integration tests for the Matter event callback mechanism to ensure that _matterEventCB is invoked correctly for all supported matterEvent_t values.
