窗体设计器：工具箱、拖放、属性与事件窗口，读写 VS 格式的 Designer.cs

- Designer.cs 在浏览器端解析为语句列表，未改动的语句保留原文：
  教材 25 个参考窗体和全部示例读入再写出逐字节不变
- 编辑操作：添加 / 删除 / 移动 / 改名控件、属性、事件、列表项；
  布局语句增删规则与 VS 一致（对全部现有文件执行无变化）
- 双击控件或事件：绑定事件并在窗体代码末尾插入处理方法，跳到代码
- 预览复用运行时的 ControlView，设计时与运行时外观一致
- 修正：窗体属性 this.ClientSize = new Size(...) 被误认成创建控件；
  示例 Designer.cs 的块头注释改为 VS 的 "// " 格式
- 测试：73 个（读写往返、布局规则、编辑操作、插入事件处理方法）
