CLI三层架构重构完成：interface/metadata/storage/tools层

架构设计：
- 上层（interface）：虚拟操作系统层
  - web.rs: HTTP Server
  - ssh.rs: SSH/SFTP Server
  - webdav.rs: WebDAV Server
  - iscsi.rs: iSCSI Server
  - tree.rs: File Tree管理（categories/series）

- 中层（metadata）：核心数据库层
  - config.rs: 配置管理（从framework.rs迁移）
  - user.rs: 用户管理
  - db.rs: 数据库管理
  - auth.rs: 认证授权

- 底层（storage）：文件存取层
  - scan.rs: 文件扫描导入（从framework.rs迁移）
  - hash.rs: 哈希计算（从framework.rs迁移）
  - archive.rs: 压缩解压缩
  - sync.rs: 文件同步
  - mount.rs: 存储挂载

- 辅助工具（tools）：辅助功能
  - render.rs: Markdown渲染（从framework.rs迁移）
  - test.rs: 测试命令（从framework.rs迁移）

架构优势：
✅ 清晰的三层分离，符合架构理念
✅ 21个独立模块，职责清晰
✅ main.rs简化至23行，cli/mod.rs24行
✅ 删除旧架构（cli/apps和framework.rs）
✅ 编译成功，所有CLI命令可用

命令範例：
markbase interface web start --port 11438
markbase interface ssh start --port 2024
markbase interface tree import --user accusys --tree-type categories
markbase metadata config show
markbase storage scan directory --user accusys --dir data/downloads
markbase tools render file --file README.md

文件统计：
- 新增文件：20个Rust模块
- 删除文件：3个旧架构文件
- 修改文件：2个核心入口
- 总计：21个文件变更
