refactor(server): 拆分 ShrimpServer → buildShrimpRouter + tokenAuth + accessor

ShrimpServer 之前一锅端 Express routes / JWT / Mongoose / 用户字段访问。
现在拆成独立部件,消费方可以单独换掉任何一块:

  - src/server/types.ts: ITokenAuth, IUserAccessor, IShrimpRouterDeps
  - src/server/jwtAuth.ts: createJwtTokenAuth(secret | options) 默认 JWT 适配器
  - src/server/buildShrimpRouter.ts: 纯函数,不直接 import jsonwebtoken/mongoose
  - src/server/ShrimpServer.ts: 装配体,protected create* factory 保留,
    子类化扩展不破坏(hand-server-2 的 AdminApi extends ShrimpServer 仍能用)
  - src/server/index.ts: 'shrimp-server/server' entry,额外暴露低阶 API

test/buildShrimpRouter.test.ts: 用 MemoryShrimpCrud + 假 ITokenAuth 拼出
独立 Router,跑通 /config /login /me 全流程 — 保证 buildShrimpRouter 不
偷偷耦合回 ShrimpServer。
