Happy to merge this, but registering some caveats/concerns for when we revisit this later -

• We've resisted adding miniflare specific features that don't have edge equivalents, but this seems like a good exception to make.
• That said, let's consider this experimental, and not make too much noise about it for now. This will definitely change in the future.
• We could probably make this work on the edge too. For module workers, we could wrap the worker in a facade that exposes a route that triggers the default.scheduled export. For service workers, we'd have to override addEventListener and wrap the fetch handler with our own thing.

Let's land this right now, and discuss further in #570.

LGTM! one formatting nit, but let's land it.
