请参考 UserRepository.kt 的写法，为 ProductRepository 实现相同的缓存逻辑

// 现有的 BaseViewModel 实现
abstract class BaseViewModel : ViewModel() {
    protected val _loading = MutableStateFlow(false)
}
// 请按此模式实现 UserViewModel

项目使用 MVVM 架构：
- data/ 层：Repository + DataSource
- domain/ 层：UseCase + Model  
- presentation/ 层：ViewModel + Activity/Fragment
使用 Hilt、Room、Retrofit

用户：应用启动时崩溃
AI：[调用 adb-logcat] 发现 NullPointerException in MainActivity:45
     user 对象为 null，建议使用 safe call (?.)

用户：列表滑动很卡
AI：[调用 adb-meminfo] 内存 450MB，ImageLoader 持有 Activity 引用
     建议使用 WeakReference 和 Glide 生命周期管理
