- Replace db.Redis/db.PrefixedKey/db.GetJSON/db.SetJSON with cachepkg.* from plugins/infra/cache
- Replace pkg/persistence/idgen with pkg/idgen (already exists)
- Replace pkg/persistence/batchwriter with pkg/batchwriter (already exists)
- Replace pkg/persistence/migrator with pkg/migrator (already exists)
- Replace pkg/persistence/logstore with plugins/domain/risk_control/logstore
- Delete defunct pkg/{persistence,cap,message_gateway,push,shared,task}

 ### 5.3 架构防线与单向依赖保障
 1. **测试脚手架绝对解耦**：底层通用的 `pkg/testhelper` 严禁反向引用任何上层业务插件。`testhelper` 维护轻量自包含的测试表脚手架，彻底杜绝包导入循环（Import Cycle）。
