How do the Godot APIs get registered in JS?

Hi,

I've been toying around with the ECMAScript module for a bit and I've been experimenting with adding Clojurescript support via [shadow-cljs](https://github.com/arundilipan/CLJS-Godot). Basically, the status is that the outputted JS from Clojurescript works in Godot, but I'm having trouble getting a REPL working. I was wondering how/at what stage does the Godot API enter `globalThis`? Also, at what point can the Javascript code be run, can it only be run ingame or no?

未指定文件、测试或入口点。首先追踪 ECMAScript 模块的 API 注册和 JavaScript 执行生命周期，然后记录 Godot API 何时进入 globalThis，以及代码是否可以在 gameplay 之外运行；包含足够的细节，以解释 REPL 可以如何初始化。
