- Enable a few more rules, fix issues. The 2 `value` issues are
false-positives.
- Add exact types for `window.pageData` and
`window.notificationSettings`.
- peerDependencyRules for eslint-plugin-github unrestricted, the plugin
works in v10, but does not declare compatibility, pending
https://github.com/github/eslint-plugin-github/issues/680.
- Added
[eslint-plugin-de-morgan](https://github.com/azat-io/eslint-plugin-de-morgan),
no violations.
