fix: IoT多设备支持 + Review Pipeline审查消息 + 意图分析快速通道优化

- IoT Provider: 重写Execute()支持多设备命令批量执行，修复persona路径
- Intent Analyzer: 新增isStrongIoTCommand快速通道，跳过LLM分析节省2-3s
- Orchestrator: parseReviewMessages()内联审查 + 快速通道扩展(chat/greeting跳过子会话)
- Gateway: SSE review_messages解析→WebSocket结构化消息转发(action/chat)
- Persona: 对话风格注入action格式指令(括号包裹动作描述)
- Frontend: sessionStore历史消息msgType映射
- 新增E2E测试脚本 + 调试标准文档 + 第4轮修复报告

E2E验证: IoT设备操控✅ Review消息拆分✅ 快速通道✅ 响应时间~3.4s
