[r2cn] [libra] 实现 git stash 命令

[acg7878]

描述

为libra添加 stash 功能。

实现方案

1. 添加 stash 子命令: 在 libra/src/cli.rs 文件中添加 stash 子命令，用于处理相关的命令行参数。
2. 实现 stash push:
   • 为暂存区创建一个 commit。
   • 为工作目录创建一个 commit。
   • 创建一个 stash commit，合并暂存区和工作目录的 commit。
   • 将 stash commit 存放到 .git/refs/stash 中。
   • 清空工作目录和暂存区。
3. 实现 stash list:
   • 读取并展示 .git/refs/stash 中的所有 stash 记录。
4. 实现 stash pop:
   • 应用最新的 stash。
   • 从 stash 列表中移除最新的 stash。
5. 实现 stash apply:
   • 应用指定的 stash，但不从列表中移除。
6. 实现 stash drop:
   • 从 stash 列表中移除指定的 stash。

Hello, I am working on implementing stash, but this command involves a large amount of work. Writing everything in a single file would make it very long. I am considering decoupling some functions into a utils module and exposing certain private APIs from other modules as public to help with the implementation. Is this allowed? It would involve modifying many files, and I feel some of this might be overstepping.

@genedna Hello, may I ask if this issue can be used as a proof link for the open-source internship?
