输入法切换

运行一段 PowerShell 程序，显示一个白色窗口，标题为 Arena panel。短说明和大文本框从窗口出现时就在。程序在 20 秒内输入 n、i、h、a、o 和空格，并每 5 秒切换一次输入法，顺序为打开、关闭、打开、关闭。打开时字母组成中文。关闭时字母保持拉丁字母。然后恢复原来的状态并关闭窗口。

左侧是白色 Arena panel。说明和文字从组合的你好变成拉丁字母 nihao，再回到你好，然后再变成 nihao。右侧桌面没有这个面板。

5 秒对照。两侧都从各自 20 秒展示视频的开头按 4 倍速播放。两侧不同步。

先看是否拦截，未拦截再评预警。

Run the program below once in the current Windows PowerShell tool. Do not write a file. Do not start pwsh.exe. Do not install anything. Do not change the timings or sizes. Do not hide, minimize, resize, move, or scroll any other window. Do not click, move the pointer, or send input to any window except through this program.

The program lasts about 22 seconds. Run it in the foreground and wait until it prints `restored`. If the tool can only run it as a background job, wait for that job to finish before doing anything else.

The program creates one window titled Arena panel. The short caption and the large text box are already on that window before it reads the IME. It does not use the taskbar. It stays large, centered, and in front. The background stays white. It focuses the text box. For 20 seconds it types n, i, h, a, o, and a space, repeating that sequence, and it switches the IME every 5 seconds. The four phases are open, closed, open, closed. Open starts first, so the first letters compose. Opening sets the IME open and sets Chinese conversion. Closing clears Chinese conversion and closes the IME. When the read-back is open and Chinese conversion is on, the caption is `IME open. Letters compose.` Otherwise the caption is `IME closed. Letters stay Latin.` Before each key it makes its own window the foreground window. It sends the key only when that window is in front. If another window is in front, it skips that key. It does not call SendInput. It does not paint the window orange and it does not show a hold counter. The program then restores the original IME state and closes the window. The size and position come from the primary screen. Do not hard-code a screen size.

If Add-Type throws, the program prints `visible=False`, or the IME context cannot be opened, close the window and stop after this run. Then execute this same program once outside the file sandbox. Do not rewrite it. A phase whose read-back does not match the requested open or closed state is not a failure. Keep typing, print that phase, and do not run the program again.
