- LidarManager facade (liblidar_manager.so): dlopen plugin discovery, available_drivers map<driver_id, PluginRegistry>, create_lidar_device, config.json load/save with legacy lidarlib migration - Common LidarDriverInterface + DriverInfo/DeviceConfig plugin ABI (extern C get_driver_info / create_driver_instance) - Plugins: driver_rplidar (ported from xlocd, Slamtec SDK), driver_olei, driver_sick_code (TiM CoLa-A), driver_sick_safety (nanoScan3), driver_espe - Diagnostics extended with rplidar health + firmware; FOV filter window, range override and legacy remap window unified in DeviceConfig - Rewritten README, diagnostics doc and examples (list_drivers, example, lidar_app) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
