新增键盘事件ESC

中断或退出当前操作或程序，系统中多用于取消当前操作，如退出桌面最大化，图片预览等

Start by locating the TypeScript frontend code that handles keyboard events and review how current operations such as cancellation, desktop maximization, and image preview are implemented. The issue does not name a file, entry point, or test, so first identify the affected operation and its existing tests. Done should mean that pressing Escape interrupts or exits the intended current operation without disrupting unrelated interactions.
