第 0 阶段：教材项目 2 任务 1 在网页中原样运行

- runtime：仿真 WinForms 子集（Form、Button、Label、TextBox、ComboBox、
  GroupBox、Timer、MessageBox、界面线程消息循环、跨线程检查）、
  教材设备类库（DeviceCtrlHelper、LED 控件）、运行器（常驻编译服务 + 运行模式）
- server：Bun + Hono，WebSocket 会话，每次运行一个进程，消息转发
- web：Vue + Naive UI，WinForms 风格窗体渲染、MessageBox、实训台 LED 屏
- 端到端测试与 100 个程序并发的压力测试
- 教材逐任务摘要（docs/教材摘要）
