The structure of the main branch in this repository has changed due to the merge of the plugins/beta branch, and conflicts appeared with this pull request. Therefore, I will close this pull request.
Since the pull request for dify-official-plugins towards v1.0.0 has already been merged, I consider my objective to be achieved.
