tino964MC/gate-whitelist — reverse-engineered prompt

Build me a simple Minecraft proxy in Go using Minekube Gate that acts as a whitelist gate in front of my server.

I want to be able to edit config.yml with the backend Minecraft server address, the proxy listen address, a friendly kick message, and a list of allowed player names or UUIDs. When someone connects, the proxy should check the whitelist before letting them through. Allowed players should connect normally, everyone else should get the custom message and the attempt should be logged clearly.

Please wire this into the existing Gate starter setup, keep the plugin code organized in the plugins folder, and make sure it runs with go run . in normal mode and debug mode. Also make sure the Dockerfile and docker compose setup still work so I can host it later without extra setup.

Keep it simple and easy to edit. Look up the current Minekube Gate docs online if you need to.
