Error while using extension Input Typer

### Description of the new feature / enhancement

Input Typer cannot type outside the Command Palette.

### Scenario when this would be used?

In Microsoft PowerToys → Command Palette, extensions like Input Typer run inside the palette window.
So when the extension “types”, Windows still thinks the Command Palette textbox has focus, not your target app (Excel, browser, Word, etc.).

👉 Result:
The text goes back into the Command Palette, instead of the place where your cursor was earlier.

Why this happens (important)

PowerToys Command Palette does not currently support returning keyboard focus to the previously active window before sending keystrokes.

### Supporting information

_No response_

Start in the PowerToys Command Palette integration used by the Input Typer extension and inspect how focus is handled before keystrokes are sent. Done means typing reaches the previously active target window rather than the Command Palette textbox; the issue names no file or test to run.
