Diniboy1123/usque ? reverse-engineered prompt

Build me a Go command line app that acts like an unofficial Cloudflare WARP client using the MASQUE protocol.

It should let me register a new account, enroll the device, and then run in a few simple modes, like a SOCKS5 proxy, an HTTP proxy, a native tunnel interface, and a port forwarding mode. I want it to read and save a config file, support ZeroTrust sign in too, and print clear help messages for each command so it feels easy to use from the terminal.

Please make it work on Linux and Windows where possible, and keep it simple to build from source. If you need to check the current docs for anything around MASQUE, Connect IP, or Wintun and TUN setup, go ahead and look it up online. I’d also like sensible defaults, good error messages, and a clean way to run it in Docker.
