/**
 * Mock 注册中心
 *
 * 所有 mock 模块在此注册，提供统一的 mockRouter 入口和开关控制。
 *
 * 开关机制：
 *   URL 参数 ?mock=0       → 关闭 mock，请求真实后端
 *   localStorage mock:enabled = 'false' → 关闭 mock
 *   默认                    → mock 开启
 *
 * 新增业务模块时：
 *   1. 在 src/mock/{module}/ 创建 seed.ts + router.ts
 *   2. 在此文件 import 并加入 routers 数组
