perf(ShowVisionRender): 图像更新与保存完全异步化，消除 UI 卡顿

- Subscribe 改为 ThreadOption.BackgroundThread，Publish() 立即返回
- UpdateRenderModuleSource 在后台线程深拷贝 ICogImage，防止像素数据被覆盖
- 提取 RequestSaveImage 方法，CreateContentBitmap + 文件 I/O 全部 fire-and-forget
- SaveImage → SaveImageAsync：移除嵌套 Task.Run，传播 CancellationToken
- 添加 _saveImageCts / _saveSemaphore / Unloaded 资源清理
- ViewModel_UpdateLayout 重置 CancellationTokenSource
