* Global proxy support for Node.js fetch (undici).
*
* Node.js native fetch does not respect http_proxy/https_proxy/all_proxy
* environment variables by default. This module sets up a global ProxyAgent
* dispatcher so all fetch requests go through the proxy when configured.
* (or no_proxy) environment variables by default. This module sets up a
* global EnvHttpProxyAgent dispatcher so fetch respects those variables.
