Feature Request

Currently only a repo with a package.json present can be recognized as a valid Hexo blog repo. i.e. in an unrecognized directory, I need to run hexo init first. It would be great to take package.yaml, which is used by pnpm into consideration.

Just realized that this is more of a feature request for Hexo-cli. Creating an issue there.
