🔧 chore(vscode): 版本号升到 0.2.210

✨ feat(vscode): 「未提交的更改」分暂存区两组、单文件暂存、隐藏测试文件
- 照源代码管理视图分「暂存的更改」「更改」两组（空的不摆，分组行写文件数），部分暂存的文件两组都有 - 「更改」组的文件行上加「暂存」按钮，走 git 扩展的 repository.add - 标题栏「隐藏测试文件 / 显示测试文件」开关，按工作区记住，藏了几个写在标题后面；测试文件的判断集中在 isTestFile - 以上只在「未提交的更改」里有：普通文件树、审查模式的行和菜单不变

cruldra	87d4360704	✨ feat(vscode): 「未提交的更改」分暂存区两组、单文件暂存、隐藏测试文件 - 照源代码管理视图分「暂存的更改」「更改」两组（空的不摆，分组行写文件数），部分暂存的文件两组都有 - 「更改」组的文件行上加「暂存」按钮，走 git 扩展的 repository.add - 标题栏「隐藏测试文件 / 显示测试文件」开关，按工作区记住，藏了几个写在标题后面；测试文件的判断集中在 isTestFile - 以上只在「未提交的更改」里有：普通文件树、审查模式的行和菜单不变	2026-09-30 06:30:54 +08:00

cruldra	7f460d1257	✨ 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	2026-09-29 23:42:10 +08:00
