Transforms an Alibaba FC HTTP request into a Stone.js IncomingHttpEvent.
FC hands over a plain request object with the body pre-read into a Buffer, so this relies only
on that shape (no node:http, no proxy-addr). The untouched request body is exposed as
metadata.rawBody; JSON and URL-encoded bodies are additionally parsed into body.
