* **New Features** * Added a standalone LVGL module and enabled LVGL support in the simulator for richer local UI testing. * **Refactor** * HAL and LVGL split into distinct modules; startup and device attach/detach flows reorganized for clearer lifecycle management. * Public APIs tightened with clearer nullability/documentation. * **Bug Fixes** * More consistent LVGL start/stop and device attach/detach behavior for improved stability.
