项目 5 补齐：旧版线程 API（Suspend / Resume / Abort）与 ListBox

- 编译时把 Thread 的 Suspend / Resume / Abort、ThreadState、Sleep、new Thread 改写成平台的
  协作式实现：被挂起或终止的线程在 Sleep、后台改控件、调设备类库、弹提示框时停下或结束；
  ThreadStateException 等行为与 .NET Framework 一致；编辑器不再提示"已过时"
- ListBox：列表项、单选、SelectedIndexChanged 先于 Click、删除选中项后取消选中；
  ComboBox 与 ListBox 共用 ListControl 和列表项集合；设计器工具箱加"列表框"
- 评分规则的"包含"对列表框检查所有列表项
- 示例：项目 5 任务 2（烟雾，线程）、任务 3（推送灾情，二维数组、两个窗体、ListBox），
  参考答案修正书上直接 Abort 挂起线程、烟雾记成"发现火情"的问题
- 一直不换行的 Console 输出攒满 4096 字符先发出，避免占满内存
- 测试：旧版线程 API、ListBox 事件顺序、两个示例的端到端和评分测试

+**第 3 阶段进展**：
+
+- 2026-10-22：项目 5 补齐（线程、ListBox）。旧版线程 API：编译时把 `thd.Suspend()` / `Resume()` / `Abort()`、`thd.ThreadState`、`Thread.Sleep`、`new Thread(...)` 改写成平台实现（只改语义上确实是 `System.Threading.Thread` 的调用，不换行，报错和异常的行号不变；编辑器里看到的仍是学生的原始代码，也不再提示"已过时"）。新版 .NET 不能从外部停住线程，平台的实现是协作式的：被挂起或终止的线程在下一个检查点停下或结束（`Thread.Sleep`、从后台线程改控件属性、调用设备类库、弹出提示框），教材的线程方法每次循环都经过这些地方；休眠中被终止的线程立即醒来结束。行为与 .NET Framework 一致的地方：线程可以挂起自己、对没启动的线程 Abort 不报错、`Resume` 没挂起的线程和直接 `Abort` 挂起的线程抛出 ThreadStateException（书上任务 2 关闭窗体时直接 `thd.Abort()`，在真实环境中也会出这个错，参考答案改为先 `Resume` 再 `Abort`，报错信息里写明这样改）。ListBox：列表项、单选、SelectedIndexChanged 先于 Click、Text 是选中项、删除选中项后取消选中；设计器工具箱加"列表框"；评分规则的"包含"对列表框检查所有列表项。新增示例：项目 5 任务 2（烟雾，线程）、任务 3（推送灾情，二维数组、两个窗体、ListBox），各有评分规则和端到端测试，共 12 个示例。
+
 **其他改进**：
 
 - 2026-10-22：代码编辑器的语言功能：代码补全（输入 `btn_Open.` 列出按钮的属性、方法、事件，只列出平台仿真了的成员）、悬停提示、参数提示（`MessageBox.Show(` 列出重载，标出正在填的参数）、停止输入 1 秒后自动检查编译错误（提示和点"运行"时一样）。语言服务是一个常驻进程，每个浏览器标签页一份工程，只更新有变化的文件。实测（限制 2 核）：50 个标签页同时检查 1.2 秒内全部完成，同时补全 0.7 秒；内存约 260 MB。
