Extension loading error when exiting the console

This is quite a specific error - I haven't seen it described yet, but please correct me if I'm wrong. Also, I'm not entirely sure it's a gdext issue. Basically, when you launch godot from the console and it transitions from there into its own thread, then after closing the console, gdext stops working. As far as I’ve tested, other extensions continue to function.

Tested only on godot 4.5 and gdext 0.24.

Reproduce the failure with Godot 4.5 and gdext 0.24 by launching Godot from a console, allowing it to transition into its own thread, and then closing the console. Investigate the extension-loading and thread-lifecycle behavior; done means gdext continues working after the console closes, as other extensions reportedly do.
