XTLS/Xray-core ? reverse-engineered prompt

I want you to build me a powerful networking toolkit in Go. The goal is to create a core engine for a proxy platform that can help people bypass internet censorship and restrictions. It should be super flexible and support a wide range of protocols like VLESS, Shadowsocks, SOCKS, Trojan, and even WireGuard, making it a universal tool for creating secure tunnels.

The main thing is that it should have advanced features to make the traffic hard to detect and block. This is meant to be the backend core, so it should be designed in a way that other developers can easily build GUI clients on top of it for all major platforms like Windows, macOS, Linux, Android, and iOS. Essentially, I'm looking for a versatile, high-performance platform for building custom, resilient proxy solutions.
