fix(agent-tab): 修复详情页 Agent tab 数据不同步问题

- 修复 updateClone 中 role→description 字段映射错误：前端发送 role
  但 Tauri agent_update 期望 description，导致角色描述从未保存
- 修复 listClones 中 userName/userRole 数据不可用：agent_list 不
  返回 userProfile，现通过 agent_get + identity_get_file 双通道
  获取用户配置数据和动态学习数据
- 修复 userAddressing 错误使用 agent nickname 作为用户称呼方式
