Your Worker can now have its own cache in front of it

Introduced Workers Cache, a tiered cache that sits in front of Cloudflare Workers. This allows Workers to act as the origin and leverage HTTP caching for server-rendered applications. Key features include configuration via Wrangler, control via Cache-Control headers, support for stale-while-revalidate and Vary headers, programmatic purges by tag or path prefix, and per-entrypoint caching. This flips the architecture from Worker-in-front-of-cache to cache-in-front-of-Worker.
