HaHafeng b47079b387 feat(iit): Phase 1.5 AI对话集成REDCap真实数据完成
- feat: ChatService集成DeepSeek-V3实现AI对话(390行)
- feat: SessionMemory实现上下文记忆(最近3轮对话,170行)
- feat: 意图识别支持REDCap数据查询(关键词匹配)
- feat: REDCap数据注入LLM(queryRedcapRecord, countRedcapRecords, getProjectInfo)
- feat: 解决LLM幻觉问题(基于真实数据回答,明确system prompt)
- feat: 即时反馈(正在查询...提示)
- test: REDCap查询测试通过(test0102项目,10条记录,ID 7患者详情)
- docs: 创建Phase1.5开发完成记录(313行)
- docs: 更新Phase1.5开发计划(标记完成)
- docs: 更新MVP开发任务清单(Phase 1.5完成)
- docs: 更新模块当前状态(60%完成度)
- docs: 更新系统总体设计文档(v2.6)
- chore: 删除测试脚本(test-redcap-query-for-ai.ts, check-env-config.ts)
- chore: 移除REDCap测试环境变量(REDCAP_TEST_*)

技术亮点:
- AI基于REDCap真实数据对话,不编造信息
- 从数据库读取项目配置,不使用环境变量
- 企业微信端测试通过,用户体验良好

测试通过:
-  查询项目记录总数(10条)
-  查询特定患者详情(ID 7)
-  项目信息查询
-  上下文记忆(3轮对话)
-  即时反馈提示

影响范围:IIT Manager Agent模块
