阶段 1 是「原样搬入、不改业务代码」，所以 ojnext 里已经死掉的东西也一起
搬了过来。这三个文件全仓零引用：

- utils/permissions.ts（usePermissions / checkRoutePermission）
- oj/ai/components/StreakStats.vue
- shared/components/IconButton.vue

确认方式：在 apps/web 全部 .ts / .vue / .json / .html / .js 里搜这五个名字
（排除文件自身）零命中；两个组件也不在自动生成的 components.d.ts 里，
permissions.ts 的两个导出同样不在 auto-imports.d.ts 里 —— 也就是说
它们连自动导入的注册都没拿到，不存在「模板里隐式用到」的可能。

permissions.ts 在 ojnext 里也是死的，不是搬运过程产生的。

vue-tsc 0 error，vite build 通过。
