feat: 数据管道注册表+宏观风险集成+管道完整性审计

1. 新增 data/pipeline_registry.json — 数据管道注册表
   - 记录每条数据流的source→consumer→end_user
   - verified字段标记是否验证通过
   - 新增组件时必须在此注册，否则体检会报未验证

2. 宏观预警集成（修复管道缺口）
   - intraday_health_check: 读macro_risk_state.json，HIGH风险时报警
   - morning_health_check: 新增管道注册表审计项
     读pipeline_registry.json，未验证的管道标为异常

3. 管道完整性自发现机制
   注册表中verified=false的管道会在每日体检中标记
   逼迫新增组件时注册管道，否则睡不好觉
