feat: cloudflare durable objects support

[pi0]

Resolves #49

This PR adds a new composable adapter for cloudflare with DurableObjects, Pub/Sub, and Hibernation support.

Composable method (vs class extension) allows automating setup and composing with other usecases in higher layers (H3, Nitro).

Note: This PR is only step 1, and needs to be better tested after release and also integrated in Nitro in order to be usable.

hey @pi0, is there a demo using this with Nitro or Nuxt? i am building a Nuxt 3 app and find it extremely difficult to go deep into Nuxt -> Nitro -> h3 / crossws to find a solution for Durable objects w/ Nuxt 3.

@vinayakkulkarni this feature is not yet supported in nitro and needs a new preset.
