fix(agent): 12 项 agent 对话链路全栈修复

深端到端验证发现 12 个问题，6 Phase 全栈修复：

Phase 5 — 快速 UX 修复:
- #9: SimpleSidebar 添加新对话按钮 (SquarePen + useChatStore)
- #5: 模型列表 JOIN provider_keys 过滤无 API Key 的模型
- #11: AgentOnboardingWizard 焦点领域增加 4 行业选项
  (医疗健康/教育培训/金融财务/法律合规)

Phase 1 — ButlerPanel 记忆修复:
- #2a: MemorySection URI 从 viking://agent/.../memories/ 修正为 agent://.../
- #2b: "立即分析对话"按钮现在触发 extractAndStoreMemories

Phase 2 — FTS5 中文分词:
- #4: FTS5 tokenizer 从 unicode61 切换到 trigram，原生支持 CJK
- 自动迁移：检测旧 unicode61 表并重建索引
- sanitize_fts_query 支持中文引号短语查询

Phase 3 — 跨会话身份持久化:
- #6-8: 重新启用 USER.md 注入系统提示词 (截断前 10 行)

Phase 4 — Agent 面板同步:
- #1,#10: listClones 从 4 字段扩展到完整映射
  (soul/userProfile 解析 nickname/emoji/userName/userRole)
- updateClone 通过 identity 系统同步 nickname→SOUL.md
  和 userName/userRole→USER.md

Phase 6 — Agent 创建容错:
- #12: createFromTemplate 增加 SaaS 不可用 fallback

验证: tsc --noEmit ✅ cargo check ✅
