v0.2.0: 解耦 shrimp-server,内置 IShrimpType 契约副本

- 拷 shrimp-server/src/IShrimpType.ts 到 src/IShrimpType.ts,头改 @syncedFrom shrimp-server contract 1.0.0
- 全部内部 import 'shrimp-server/types' → 本地 './IShrimpType'(各文件按相对路径)
- src/index.ts 加上类型契约的 re-export(ShrimpCode/ShrimpError/枚举/全部 interface),消费侧从 'shrimp-admin' 一处拿到
- 删 dependencies.shrimp-server,前端 bundle 不再牵 mongoose/express

为什么不直接 import 'shrimp-server':
  shrimp-server v0.6.0 收单入口后,入口含 mongoose/express,前端会被 vite 牵进 bundle。
  契约副本 + 版本号对照是低频改动场景的更干净选择。
