fix: allow Web Store extension native messaging

- Add the Chrome Web Store extension ID alongside the keyed testing ID.
- Register both extension origins in the native messaging host manifest.
- Update install output so users can distinguish testing and Web Store IDs.
- Add CLI coverage for the generated allowed_origins list.
