Phase 0: 项目初始化与基础架构

- 创建 .NET 8 WPF 项目 PersonalToolBox
- 引入 NuGet 包: CommunityToolkit.Mvvm, System.Text.Json, Microsoft.Extensions.DependencyInjection
- 建立 MVVM 目录结构: Models/ ViewModels/ Views/ Services/ Helpers/
- 实现 LogEntry 模型 (时间/日志级别/内容)
- 实现 ILogService 接口与 LogService (线程安全, 通过 Dispatcher 推送到 UI)
- 配置 DI 容器 (App.xaml.cs) 注册日志服务和主窗口
- 添加 .gitignore 文件
