v1.3-rc

This release is the 1.3RC (Release Candidate) version, featuring the following key updates:

1. The plugin's interface has been optimized by changing two lines into one, thereby reducing its occupied space. #26
2. Multiple bugs have been addressed and resolved. #39, #42, #43.
3. Add a *_code_update.zip file in the release. This file only contains the code portion, which greatly reduces the file size and can significantly reduce the download time for users who only need to update the code.
