Native Rust support on Cloudflare Workers

Introduced the `worker` crate for native Rust support on Cloudflare Workers, enabling idiomatic Rust development via WebAssembly. This eliminates the need for JavaScript trampolines and provides Rust-friendly APIs for Workers features like KV stores and Durable Objects. The post includes a code snippet demonstrating Rust Worker implementation and instructions for using `wrangler` to generate Rust projects.
