Chat Application

This is a real-time chat application where users can register, log in, and communicate within different chat rooms. The application uses JWT authentication for secure access, and real-time messaging is handled through WebSockets. The project is built with Angular and Tailwind CSS for the frontend, and Java Spring Boot with Kafka for the backend.
