Until now, the user code response it's buffered and serialized. This is mismatching how Vercel works these days. This PR enables streaming response in `vc dev` for Edge/Serverless. As part of the implementation, the `node-bridge` which spawns a process to consume the user code is not necessary anymore. Some necessary files (like HTTP server helpers) have been moved to live in node builder package instead. --------- Co-authored-by: Ethan Arrowood <ethan.arrowood@vercel.com> Co-authored-by: Sean Massa <EndangeredMassa@gmail.com>
