Feature: Interactive 'kit' command for common Git operations

[samzong]

A new top-level command, , is proposed to provide a better user experience for developers who need to perform common but sometimes hard-to-remember Git operations.

Core Requirements

• When a user runs , the tool should display an interactive menu.
• This menu should present a list of "lifesaving" or shortcut commands, each with a clear and simple description.
• The user should be able to navigate this list (e.g., with arrow keys) and select an option.
• Upon selection, the corresponding Git command should be executed directly.

Initial Operations for the Menu

The initial list of operations should include:

• Undo the last commit (keep changes staged)
• Undo the last commit (keep changes in working directory)
• Discard all local changes in the working directory
• Stash all current changes
• Apply the most recent stash
• Amend the last commit (edit message or add files)

kit can also have an abbreviation, like gmc k.

git reset --soft HEAD~1

如果使用了 git reset --hard HEAD~1 ，也不用着急，可以使用 git reflog 查找 git 本地操作日志，里面记录了每一次的 HEAD 变更

git reset --hard 到对应的 commit 即可
