- * useStore.ts — 统一 Store 接口（兼容 Tauri 和 Web 双模式）
- *
- * 设计：
- *   - 检测 __TAURI__ 环境，决定走 invoke 还是直接调 TS store
- *   - 暴露与现有 store 相同的方法签名（88 处组件调用零改动）
- *   - 返回 reactive ref（与 Vue 响应式兼容）
- *
- * Web 模式：直接 return store（现有行为，零改动）
- * Tauri 模式：返回封装对象，内部 invoke Rust 命令

-/* =====================================================================
- * backend.ts — 持久化后端抽象层
- *
- * store 只管内存状态 + Op Log，持久化通过 Backend 接口抽象。
- * 三个实现：
- *   - LocalBackend   （localStorage，Web 版当前模式）
- *   - TauriBackend   （Rust 文件系统，桌面版，B4 实现）
- *   - CloudBackend   （HTTP API，云端版，C0 实现）
- *
- * 设计原则：
- *   - 接口只管读写数据，不管状态逻辑（状态逻辑在 store）
- *   - 所有方法返回 Promise（TauriBackend/CloudBackend 天然异步）
- *   - LocalBackend 内部用 localStorage 但包装为 Promise（统一接口）
