build, fix, feat, refactor: 优化长列表性能，新增注册表并发校验，升级v5.1.0

- 前端引入@tanstack/react-virtual虚拟列表库，重构PathTable与MergePreview组件，优化大量路径条目下的渲染性能
- 为后端注册表保存接口添加原始路径比对逻辑，防止并发修改导致的配置覆盖，同步更新前端保存逻辑传递原始路径参数
- 替换core模块手动编写的Windows API FFI声明为windows-sys官方库，简化代码维护
- 完善单元测试，新增空数组处理、边界场景的测试用例
- 更新项目依赖与锁定文件，将版本升级至v5.1.0
- 新增项目代码架构审查文档
