fix(admin): 微收口（注释/角色防御/dev 约定文档/husky 移除）

- routesAlias.ts 修复 clean:dev 打坏的块注释
- system-manage.ts menus/simple 标注死代码（backend 模式前置条件）
- /me 映射非 staff roles 兜底 R_USER，防空数组跳过菜单角色过滤
- 新增 README-dev.md：config-object 签名/URL 无 /api 前缀/Bearer 归映射层/v-html 红线
- package.json 删 husky prepare（防 pnpm install 改写 core.hooksPath）
