Research direction

Examine the current implementation of `npm init ava` to understand how it generates the package.json and CLI flags. Look for the template or logic that sets the `"test"` script. The change requires modifying that logic to output `"ava": {"serial": true}` under the `ava` key in package.json instead. Check the repository's source code, likely in `index.js` or a generator file, and refer to the AVA configuration documentation for the expected format.
