txthinking/brook ? reverse-engineered prompt

Build me a cross platform network tool like Brook that can run as both a server and a client, with a simple command line experience and support for making secure network connections over different transports. I want it to be able to start a server with a password, connect from another device, and route traffic through it like a proxy or VPN style tool. It should work on Linux, macOS, Windows, Android, iOS, and OpenWrt where possible, and have clear help text and sane defaults so it is easy to set up. If it needs current docs or platform specific details, look them up online and follow the project style in the repo. Make the main flows feel polished, so someone can install it, start a server, connect a client, and use it without needing to understand networking jargon.
