Introduced a hybrid model for Node.js API compatibility in Cloudflare Workers, combining native C++/TypeScript implementations for core APIs (like Buffer, AsyncLocalStorage, Crypto) with polyfills (via unenv) for others.

This significantly enhances the ability to leverage the existing JavaScript ecosystem within the Workers runtime.
