✨ feat(vscode): 代码阅读侧栏加「未提交的更改」筛选

- 标题栏新按钮「未提交的更改」：树里只剩工作区各 git 仓库里没提交的文件（暂存、没暂存、未跟踪、合并冲突），每个有改动的仓库一个根，跟着 git 状态自动重摆；上色和徽标交给 VS Code 自带的 git 装饰
- 两种筛选互斥，由 TreeFilters 统一管，上下文键合并成 superpowers.codeReader.filter（review / uncommitted）
- 改动文件树改成多根，buildChangedTree 挪到 explorer/changedTree 并改吃 {path, change}
- 内置 git 扩展 API 的类型和加载抽到 src/git/gitApi、gitExtension，提交按钮的监听也改用它
- 文件注释按文件所在的工作区文件夹记，不看树从哪个根摆下来
