feat: add /ego-mgr slash command

新增 /ego-mgr slash command 支持：
-  - 获取字段值
-  - 设置字段值
-  - 列出所有字段名
-  - 删除字段
-  - 添加 Agent Scope 字段
-  - 添加 Public Scope 字段
-  - 显示所有字段和值

实现细节：
- 创建 EgoMgrSlashCommand 类处理所有子命令
- 使用 pcexec 工具调用 ego-mgr 二进制
- 自动注入 AGENT_ID, AGENT_WORKSPACE, AGENT_VERIFY 环境变量
- 支持带空格的字段值
- 友好的错误提示和用法说明
