Subject: [PATCH] fix: add windowsHide: true to spawn in runCommandWithTimeout

Fixes flashing conhost.exe windows on Windows when exec module spawns
child processes. The windowsHide: true option prevents orphaned conhost.exe
processes and eliminates disruptive terminal window flashing.

Closes #18613
