Is this version work normally on OSX? Maybe you should clone, checkout this branch, and final run it though pnpm install and pnpm tauri dev

There are 3 points to be tested:

• It should display setup page on first start, and the version of python and gcc will be display after you enable it.
• Right click the tab header after create, change the language between python and c++ to check if the language work normally.
• Change default language in Preference, and check whether the new file be create in specific language

The language server starter is hardcoded that did not follow configuration. It should be changed in next commit.

Well, I do not know how to design its interface now
