Real-Time Chat Application with Publisher-Subscriber Setup in Go

This application implements a basic publisher-subscriber mechanism in Go for real-time chat. Users can join individual channels to send and receive messages. It supports creating rooms based on channel names, broadcasting messages to all nodes, and connecting over a socket-based communication system.
