This implements the WebUSB-based web installer using fastboot.js to act as a fastboot client. A bare minimum UI with a plain-text status/progress caption for each step is included, as well as a plain button to trigger it and basic error handling. WebADB has been removed now that we are only using fastboot.js. Initial features: - Unlocking and locking the bootloader - Downloading the latest GrapheneOS release available for the device - Flashing the factory images zip - Reusing USB connections
