- 新增WechatService（企业微信推送服务，支持文本/卡片/Markdown消息） - 新增WechatCallbackController（异步回复模式，5秒内响应） - 完善iit_quality_check Worker（调用WechatService推送通知） - 新增企业微信回调路由（GET验证+POST接收消息） - 实现LLM意图识别（query_weekly_summary/query_patient_info等） - 安装依赖：@wecom/crypto, xml2js - 更新开发记录文档和MVP开发计划 技术要点： - 使用异步回复模式规避企业微信5秒超时限制 - 使用@wecom/crypto官方库处理XML加解密 - 使用setImmediate实现后台异步处理 - 支持主动推送消息返回LLM处理结果 - 完善审计日志记录（WECHAT_NOTIFICATION_SENT/WECHAT_INTERACTION） 相关文档： - docs/03-业务模块/IIT Manager Agent/06-开发记录/Day3-企业微信集成开发完成记录.md - docs/03-业务模块/IIT Manager Agent/04-开发计划/最小MVP闭环开发计划.md - docs/03-业务模块/IIT Manager Agent/00-模块当前状态与开发指南.md
