Add the ability to select any commit to see the diff on the branch in changes. Like the way we can see last commit but would be nice to select any commit on the branch we are working on

从桌面应用的 /chat 更改视图开始，跟踪查看最后一次提交 diff 的现有行为。确定当前分支上的提交是如何列出的，以及所选提交是如何传递给 diff 视图的。当可以选择工作分支上的任何提交并一致地显示其 diff 时，即表示完成。
