Describe the Bug

When attempting to use Durable Objects with the astro/cloudflare adapter, class definitions of the objects are not exported. This results in runtime errors.

The root cause is that only the fetch handler is currently exported
https://github.com/withastro/adapters/blob/main/packages/cloudflare/src/entrypoints/server.ts#L94

What's the expected result?

The adapter needs to expose a way to export additional handlers (e.g. for cron and email) as well as durable object classes.
