Smart Ring Dashboard: direct BLE access to generic smart rings

Smart Ring Dashboard implements direct Web Bluetooth access to Anko/Jring and Colmi/Yawell smart rings using documented BLE packet formats. Its protocol reference describes GATT services, commands and response layouts, while the browser app displays heart rate, activity, sleep and oxygen readings.
