Problem statement

While debugging, VS Code allows you to type commands into the console, which currently (in my testing) does nothing.

Proposed solution

Godot 4.4 will be getting a REPL, so I would like for VS Code's console to have similar functionality!

There was partial repl support added by a contributor last year, but there may have been a regression. Thanks to @MichaelXt we now have a godot-in-the-loop test suite, so we can try to get that working again and then finish what's missing.

I've been using a fork of a plugin by jitspoe to add an in-game debug console which works similarly to source/creation engine games. Would it be out of scope to suggest a similar API where custom "commands" can be created? Or maybe "aliases", which can act as shortcuts to longer commands - e.g. instead of typing $/root/MyNode.my_function() i could type myfunction
