fix(identity): 3 项根因级修复 — Agent ID 映射 + user_profile 读取 + 用户画像 fallback

Issue 2: IdentityFile 枚举补全 UserProfile 变体
- get_file()/propose_change()/approve_proposal() 补全 match arm
- identity_get_file/identity_propose_change Tauri 命令支持 user_profile

Issue 1: Agent ID 映射机制
- 新增 resolveKernelAgentId() 工具函数 (带缓存)
- ButlerPanel 使用 kernel UUID 替代 SaaS relay "1" 查询 VikingStorage

Issue 3: 用户画像 fallback 注入
- build_system_prompt 改为 async，identity user_profile 为默认值时
  从 VikingStorage preferences 路径查询最近 5 条记忆作为 fallback
- intelligence_hooks 调用处同步加 .await
