QuizzityMC/EaglerServer-1.12 ? reverse-engineered prompt

Build me a simple EaglerCraftX 1.12 server setup that I can run from this repo and use right away.

I want it to work like the README says, where I can start the proxy and the main server, forward port 8081, and then connect from the client with a wss link. Make the setup as smooth as possible for someone who is not super technical, so it should be easy to launch in Codespaces or a normal host too.

If anything in the repo needs to be wired up better, fix it so the server actually starts cleanly and the instructions match what a real person would do. Look up current docs online if you need to, and keep the whole thing focused on getting a working playable EaglerCraft server online with the least amount of fuss.
