hailin 16cc0e4c08 feat(agents): implement multi-agent collaboration architecture 
借鉴 Claude Code 的架构模式，将单一 Agent 重构为 Coordinator + 6 Specialist 多 Agent 协作系统。

## 新增文件 (36个)

### 架构设计文档 (docs/architecture/, 12个)
- 00-overview.md ~ 11-prompt-templates.md: 完整架构设计，覆盖所有 Agent 的详细设计、
  Prompt 模板、协作流程、工具并发系统、动态上下文注入

### 多 Agent 系统 (infrastructure/agents/, 23个)
- coordinator/coordinator-agent.service.ts: 主协调器，替代 ClaudeAgentServiceV2
- coordinator/agent-loop.ts: 核心递归 async generator 循环（参考 Claude Code aM()）
- coordinator/context-injector.service.ts: 动态上下文注入（8种上下文类型按优先级注入）
- specialists/base-specialist.service.ts: Agent 基类（封装 Claude API 调用 + prompt 缓存）
- specialists/policy-expert.service.ts: 政策专家 (Sonnet 4, temp=0)
- specialists/assessment-expert.service.ts: 评估专家 (Sonnet 4, temp=0)
- specialists/strategist.service.ts: 策略顾问 (Sonnet 4, temp=0.3)
- specialists/objection-handler.service.ts: 异议处理 (Sonnet 4, temp=0.2)
- specialists/case-analyst.service.ts: 案例分析 (Haiku, temp=0)
- specialists/memory-manager.service.ts: 记忆管理 (Haiku, temp=0)
- prompts/coordinator-system-prompt.ts: 协调器 Prompt（1095行，13章）
- prompts/{policy,assessment,strategist,objection,case,memory}-*-prompt.ts: 各专家 Prompt
- tools/coordinator-tools.ts: 16个工具定义（6 Agent 调用 + 10 直接工具）
- tools/tool-execution-queue.ts: 并发执行队列（isConcurrencySafe 控制并行/串行）
- types/agent.types.ts: Agent 配置、输入/输出类型定义
- types/stream.types.ts: 流式事件类型（含 agent_start/complete/coordinator_thinking）
- types/context.types.ts: 上下文注入类型
- agents.module.ts: NestJS 模块注册

### 前端 Agent 状态展示 (1个)
- AgentStatusIndicator.tsx: 多 Agent 工作状态组件（含动画）

## 修改文件 (15个)

### 后端集成
- conversation.service.ts: 切换到 CoordinatorAgentService
- conversation.gateway.ts: 新增 agent_start/agent_complete/coordinator_thinking 事件
- claude.module.ts: 引入 AgentsModule
- agents.module.ts: 注册 ImmigrationToolsService（复用旧版生产测试的工具实现）
- knowledge-client.service.ts: 新增 search()/getUserContext() 便捷方法

### 旧代码标记 @deprecated
- claude-agent.service.ts, claude-agent-v2.service.ts
- strategy-engine.service.ts, intent-classifier.ts, response-gate.ts

### 前端适配
- chatStore.ts: 新增 ActiveAgent/CompletedAgent/CoordinatorPhase 状态
- useChat.ts: 新增 WebSocket 事件处理
- ChatWindow.tsx: 集成 AgentStatusIndicator
- globals.css: 新增 agentPulse/agentSlideIn 动画

### 共享类型
- conversation.types.ts: 新增 AGENT_START/AGENT_COMPLETE/COORDINATOR_THINKING 事件

## 核心设计决策

1. **新旧结合**: Coordinator 的 10 个直接工具委托给旧版 ImmigrationToolsService
   （经过生产测试的 Google Search、汇率 API、新闻 API 等），6 个 Agent 调用工具
   走新的 Specialist Agent 系统
2. **递归 async generator**: agent-loop 支持流式输出 + 工具递归 + 成本/轮次控制
3. **并行 Agent 执行**: ToolExecutionQueue 根据 isConcurrencySafe 自动并行/串行
4. **Prompt 缓存**: 所有 Agent 的 system prompt 使用 cache_control: ephemeral
5. **速率限制重试**: 429/529 指数退避，最多 2 次
6. **向后兼容**: LegacyConversationContext 类型别名，StreamChunk 扩展不破坏现有结构
