feat(bookmark): 添加文件夹树结构导入导出接口

新增 `/bookmarks/v1/folder/serial` 接口，支持文件夹树结构的压缩导出与解压导入。
同时完善了相关响应结构体定义，如 ImportResponse 等。

refactor(bookmark): 重命名配置文件并调整字段命名

将 `config/api.yaml` 重命名为 `config/bookmark.yaml`，并统一将 parent_path_id 字段
更名为 parent_id。此外，更新 API 鉴权头名称为 X-BookMark-Token。

feat(bookmark): 实现文件夹挂载管理功能

新增以下三个接口用于管理文件夹挂载：
- GET `/bookmarks/v1/folder/{id}/mount` 获取挂载信息
- POST `/bookmarks/v1/folder/{id}/mount` 挂载文件夹
- DELETE `/bookmarks/v1/folder/{id}/mount` 取消挂载

新增相关结构体定义：MountResponse、MountInfo。

feat(vfs): 初始化虚拟文件系统 API 配置

新增 `config/vfs.yaml` 和 `config/vfs_cfg.yaml` 配置文件，定义 VFS 相关接口和代码生成规则。
接口包括文件/目录的创建、读取、更新和删除操作，并引入新的安全头 X-VFS-Token。

chore(config): 忽略 data 目录并更新生成路径

.gitignore 中新增忽略 data/ 目录。同时更新 bookmark 和 vfs 的代码生成输出路径分别为
`./gen/bookmarks/gen.go` 和 `./gen/vfs/gen.go`。

chore(deps): 引入 casbin、gopsutil 等依赖库

go.mod 中新增 casbin 权限控制、gopsutil 系统监控等相关依赖。
