v0.5.0: 重新组织目录结构,按职责拆分

- Shrimp.ts (875 行) 按类拆分到 Shrimp/(7 文件: Shrimp, ShrimpModule, ShrimpTableModule, ShrimpPower, ShrimpCrud, UserRoleModule, OperationLogModule)
- forMongo/: MongoShrimpCrud + MongoShrimp(原 ShrimpServer 的 mongo 装配部分,无 express)
- forExpress/: buildShrimpRouter + jwtAuth + types
- main/: index(0 依赖核心) + expmon(express+mongo 整合,导出 ShrimpServer) + types(纯协议)
- 入口子路径 server → expmon(express+mongo 整合方案命名更准确)
- 删除冗余的 index.ts / core.ts(合并为 main/index.ts)
