A looser implementation of fetch that bypasses Node.js' built-in fetch.
Some implementations (specifically ones that provide undici-based shims)
or some versions of Node.js may ship with a built-in version of undici
that's older and/or missing patches.
This implementation of fetch uses built-ins as much as possible,
using global Request, Response, and Headers, whether they're provided
by a polyfill or by Node.js itself.
However, it's a looser and more permissive implementation that calls
into node:http and node:https instead.
Think of it as @remix-run/web-fetch, but lighter.
