Feature Request: Built-in support for edge runtime APIs

[fbwe425]

Description

With the rise of edge computing platforms (Cloudflare Workers, Deno Deploy, Vercel Edge Functions), it would be valuable if Node.js could provide a subset of APIs compatible with these runtimes.

Proposed Solution

1. Add a --edge-compat flag to enable edge-compatible mode
2. Support Web Crypto API, Fetch API, and Streams API natively
3. Provide a way to polyfill or shim edge-specific APIs
4. Generate deployment manifests for popular edge platforms

Benefits

• Write once, deploy anywhere (Node.js and edge)
• Easier migration from serverless to edge
• Better interoperability between runtimes
• Unified testing experience

Additional Context

This would make Node.js a universal runtime that can target both traditional servers and edge platforms.
