Reference created for navigator.serviceWorker.register(new URL(...), { scope }). It resolves
the URL to the service-worker source and wraps it in a ServiceWorkerEntryModule (carrying
the scope) so the source is discoverable in the page’s module graph (but not bundled into it).
A marker module that wraps a service-worker entry source plus its registration scope. It
carries the inner source so next-api can discover it in the module graph and compile it
standalone.
The root-served file name for a service worker registered at scope. One worker is supported
per scope; the scope is encoded into the (flat, root-served) file name so distinct scopes
get distinct files.
