Describe the Bug

experimental.cache: waitUntil missing from CacheProvider.onRequest context when using the Cloudflare adapter.

The docs define onRequest context as:

context: { request: Request; url: URL; waitUntil?: (promise: Promise<unknown>) => void }

But waitUntil is missing in both the type and at runtime when using the Cloudflare adapter.

dist/core/cache/types.d.ts — waitUntil is not in the type:

onRequest?(context: {
  request: Request;
  url: URL;
}, next: MiddlewareNext): Promise<Response>;

Runtime — typeof context.waitUntil is "undefined" inside a custom provider's onRequest.

Without it, cache writes in Cloudflare Workers must be awaited before the response is sent, adding latency on every cache miss. The correct pattern — context.waitUntil(cache.put(...)) — is currently broken.

What's the expected result?

context.waitUntil should be available, matching the documented signature, so that cache writes can be handed off as background work.
