Add unlisted script to web_accessible_resources automatically

Feature Request

It would be nice to have the appropriate web_accessible_resources entry added automatically based on the matches property.

// main-injected.ts
export default defineUnlistedScript({
  matches: ["https://example.net/*"],
  main() {
    // ...
  },
});

The entry can probably be added with use_dynamic_url: true by default.

Perhaps HTML pages could also have something like the following for the same effect:

<meta name="manifest.matches" content="['https://example.net/*']" />

Thanks!

What are the alternatives?

Keeping things as-is.

Start by tracing defineUnlistedScript and how the matches property is represented in the generated extension manifest. Compare the requested automatic web_accessible_resources entry, including use_dynamic_url, with the proposed HTML meta form; done means supported scripts receive the correct entry without manual manifest changes.
