HTTP endpoints are almost undocumented #319
Description
The documentation only shows a few example responses but the meaning of each property of the responses are not documented.
For instance, what url means in the response of /json/list? I guess this property is only for presentation purpose about the location where the isolate meant to work on, such as the address of a browser tab or the module specifier passed to the Worker constructor, but there's no assurance for expectation like this currently.
Is there any OpenAPI definition or similar elsewhere I'm missing?
