Resource disposal inside component-exported Resources does not trigger

[vados-cosmonic]

Resources that are exported by components should have their disposal functions ([Symbol.dispose]() in JS) called when they are removed from the embedder's scope.

It's unclear if it's simply jco embedders (i.e. transpiled components) that are failing to do this, but a simple use (see #988 ) does not print the disposal message as expected.

Let's ensure that transpiled code properly disposes of resources that are in components. To illustrate, the following code:

{
    using ex1 = new resources.Example();
    console.log('Hello from ex1:', ex1.hello('ex1'));
}

Should trigger the [Symbol.dispose]() on the Example resource inside the component.
