* feat: 使用选区截图时，不清除 Strokes（Keep it on screen） * fix: 浮动栏选区截图前强制保持墨迹可见 * fix: 避免选区截图回滚 inkCanvas 运行时状态 * fix: 截图前退出并在结束后恢复批注状态 * fix: 截图流程改用轻量批注暂停避免副作用 * feat: 选区截图添加包含墨迹开关 * fix: 避免选区截图墨迹重复渲染 * fix: 全屏基础截图排除主窗口后再叠加墨迹 * fix: 隐藏浮动栏后再进入选区截图 * fix: 添加到白板时不强制恢复浮动栏可见性 * fix: 防止重复启动选区截图实例 * fix: 仅在白板接管成功后跳过浮动栏恢复 * feat: 选区截图时实时预览包含墨迹开关 * fix: 合并截图选择器OnClosed逻辑避免重复定义
