[Feature] Option to hide terminal after target launch

### Request Overview

After Build/Run/Edit session, I often find myself hiding a terminal by Close button or shortcut, because Launch Target action re-uses the integrated terminal and it re-appears again on every Launch.

Could we have an option to close it after the target quits? Or to keep the terminal hidden if it was closed before?
I didn't found something obvious.

### Additional Information

_No response_

Start by tracing the Launch Target action and the integrated-terminal handling in the extension. Compare the requested behaviors: closing the terminal after the target quits, or keeping it hidden when it was already closed. Done means a configurable option implements the chosen behavior without preventing later terminal use.
