fix(intelligence): Heartbeat 统一健康系统 — 6处断链修复 + 健康面板 + SaaS自动恢复

Rust 后端 (heartbeat.rs): - 告警实时推送: OnceLock<AppHandle> + Tauri emit heartbeat:alert - 动态间隔: tokio::select! + Notify 替代不可变 interval - Config 持久化: update_config 写入 VikingStorage - heartbeat_init 从 VikingStorage 恢复 config - 移除 dead code (subscribe, HeartbeatCheckFn) - Memory stats fallback 分层处理新增 health_snapshot.rs: - HealthSnapshot Tauri 命令 — 按需查询引擎/记忆状态 - 注册到 lib.rs invoke_handler 前端修复: - HeartbeatConfig handleSave 同步到 Rust 后端 - App.tsx 读 localStorage 持久化配置 + heartbeat:alert 监听 + toast - saasStore 降级后指数退避探测恢复 + saas-recovered 事件 - 新增 HealthPanel.tsx 只读健康面板 (4卡片 + 告警列表) - SettingsLayout 添加 health 导航入口清理: - 删除 intelligence-client/ 目录版 (9文件 -1640行, 单文件版是活跃代码)

-/**
- * Intelligence Layer Unified Client
- *
- * Provides a unified API for intelligence operations that:
- * - Uses Rust backend (via Tauri commands) when running in Tauri environment
- * - Falls back to localStorage-based implementation in browser/dev environment
- *
- * Degradation strategy:
- * - In Tauri mode: if a Tauri invoke fails, the error is logged and re-thrown.
- *   The caller is responsible for handling the error. We do NOT silently fall
- *   back to localStorage, because that would give users degraded functionality
- *   (localStorage instead of SQLite, rule-based instead of LLM-based, no-op
- *   instead of real execution) without any indication that something is wrong.
- * - In browser/dev mode: localStorage fallback is the intended behavior for
- *   development and testing without a Tauri backend.
- *
- * This replaces direct usage of:
- * - agent-memory.ts
- * - heartbeat-engine.ts
- * - context-compactor.ts
- * - reflection-engine.ts
- * - agent-identity.ts
- *
- * Usage:
- * ```typescript
- * import { intelligenceClient, toFrontendMemory, toBackendMemoryInput } from './intelligence-client';
- *
- * // Store memory
- * const id = await intelligenceClient.memory.store({
- *   agent_id: 'agent-1',
- *   memory_type: 'fact',
- *   content: 'User prefers concise responses',
- *   importance: 7,
- * });
- *
- * // Search memories
- * const memories = await intelligenceClient.memory.search({
- *   agent_id: 'agent-1',
- *   query: 'user preference',
- *   limit: 10,
- * });
- *
- * // Convert to frontend format if needed
- * const frontendMemories = memories.map(toFrontendMemory);
- * ```
