让只用 Shrimp 核心(RPC + 模块声明 + 内存 CRUD)的项目不必装
express / mongoose / bcrypt / jsonwebtoken,显著降低 install 时间。
- src/core.ts:0 重依赖入口(Shrimp / MemoryShrimpCrud / 类型)
- src/server.ts:在 core 之上再导出 ShrimpServer + MongoShrimpCrud
- package.json:加 exports 字段 + peerDependenciesMeta.optional
- Shrimp.ts:bcrypt 改 lazy import,只有走 Password 字段才触发
- MemoryShrimpCrud.populateItems:接 crudRegistry 参数(对齐 Mongo)
- ShrimpTableModule 构造时自动登记 crudRegistry,业务无需手动 wire
- 新增 test/crudRegistry.test.ts 验证自动登记 + relation 自动 populate
BREAKING: import { ShrimpServer } from 'shrimp-server' 不再可用,
请改为 'shrimp-server/server'。
