feat(commands): 实现命令 CRUD 完整功能

Core:
- 新增 CommandManager 类，支持创建、更新、删除命令
- 验证命令名称防止路径遍历攻击
- 自动生成 Markdown 文件（含 YAML frontmatter）
- 内置命令保护（不可修改/删除）

Server:
- POST /api/commands - 创建命令
- GET /api/commands/:name/content - 获取命令完整内容
- PUT /api/commands/:name - 更新命令
- DELETE /api/commands/:name - 删除命令

UI:
- 新增 createCommand、updateCommand、deleteCommand、getCommandContent 函数
- 新增 CreateCommandInput、UpdateCommandInput、CommandContent 类型
