 * Stock service worker script.
 * Users can provide their own sw.js if they need to extend the functionality of the service worker.
 * Ideally, this will be registered under the scope in uv.config.js so it will not need to be modified.
 * However, if a user changes the location of uv.bundle.js/uv.config.js or sw.js is not relative to them, they will need to modify this script locally.
