Hey @quantizor, thanks for proposing a new entry to the directory! 👍

Few suggestions to fix CI and prepare this to merge:

• entries need to have at least one supported platform from the list here - https://github.com/react-native-community/directory?tab=readme-ov-file#-platforms - so let's add at least one, only stand-alone dev tools can omit that
• remove npmPkg line - it's mostly for packages in monorepo or situation when repository name does not match package name
• remove website from examples - we extract website/homepage from package.json homepage field, or from GitHub repository metadata, also we expect examples to be code projects or Snacks, see: https://github.com/react-native-community/directory?tab=readme-ov-file#examples
