Summary

On Windows, launching OpenCLAW causes background gateway processes to briefly open command prompt windows, resulting in visible screen flickering.

Steps to reproduce

Launch OpenCLAW on a Windows system using a standard setup. Observe the screen during startup as the gateway initializes.

Expected behavior

The gateway should start fully in the background without opening or displaying any visible command prompt windows.

Actual behavior

Command prompt windows repeatedly appear and disappear very quickly during execution, creating a noticeable flickering effect on screen.
