Get a list of Ember apps on the page

$edb.getApps() => [...]

Interesting point. It did not even occur to me, that there may be multiple apps running on the same page.

How are other app-instance-specific helpers supposed to behave, when there's multiple app instances?

I'd say in the majority of cases, there's only one app instance per page, so it'd be great if the helper would then default to using that app instance. Or maybe you can set a default context instead of explicitly passing the app in the helper.

What if we make these things return AppDebug?

interface EmberDebug {
  getApps(): AppDebug[];
  getAppByName(name: string): AppDebug | null;
}

interface AppDebug {
  name: string;
  app: Ember.Application;
  instance: Ember.ApplicationInstance;
  lookup(key: string): unknown;
  renderTree: RenderTreeDebug;
}

...

So you can do $edb.getAppByName('my-app').lookup('store:main'), etc. I suppose we can have a getMainApp() too, but what does the "main" app really mean?
