[General] Need a "git history" view.

**Category:** General

Need a "git history" view. There's a Changes view but no git log. Add a way to browse commit history on the side — possibly integrated into the Changes view rather than standalone.

首先检查现有的 Changes 视图，因为 issue 建议在那里集成提交历史，而不是添加一个独立屏幕。确定应用如何在更改旁边提供可浏览的 git log；当用户可以打开该视图并从侧边浏览提交历史时，即视为完成。

由索引模型根据 Issue 内容生成。
