No.

Is there anything you'd like reviewers to focus on?

I left two things for follow-ups (I'll open separate issues when this is merged):

1. eslint-plugin-jsdoc rules are disabled for now. Enabling these rules will need special attention because we're using JSDoc to generate types.
2. I'm not sure if we're getting all checks from eslint-plugin-n because linted files are not published.

Rather than using eslint-config-prettier, could we just create a config in eslint-config-eslint that doesn't include formatting rules?

Good idea! I'll make a PR for this in eslint/eslint.
