COP - xr_3da process enters stopped state upon launching

Describe the bug
When launching OpenXRay with ./bin/xr_3da, a glitched window briefly spawns and the process immediately suspends into a Stopped state. Launching the binary with setsid bypasses the suspension and allows it to run normally.

To Reproduce
Steps to reproduce the behavior:

1. Compile OpenXRay with -DCMAKE_BUILD_TYPE=Release.
2. Open a standard terminal window.
3. Run ./bin/xr_3da.
4. See error: A glitched window appears, followed by the process entering a Stopped state in the terminal.

Expected behavior
The engine should initialize its graphical window and start cleanly without triggering terminal session suspension.

[26]+  Stopped                    bin/xr_3da

Desktop:

• OS / Window Manager: Void Linux with dwm (Xorg)
• GPU drivers: NVIDIA GTX 970 with proprietary drivers (v580)
• Build: Release, dev branch (commit 42e66412)

Additional context

• Whenever it hits that Stopped state, the shell doesn't actually close the game, it just leaves it hanging in the background and processes stack up in the process list if you try launching it a few times.
• The issue only occurs when launching directly from a windowed terminal. Full-screening the terminal or using setsid prevents the suspension.
• This issue also happens on build Release Master Gold.
• glxinfo confirms OpenGL 4.6 support.

Start by reproducing the launch from a standard windowed terminal with the Release build and ./bin/xr_3da, comparing it with setsid and fullscreen-terminal launches. Review the engine startup path around the graphical window initialization and the terminal's Stopped state under Xorg/dwm. Done means direct launch initializes the game window and remains running without requiring setsid.
