Jetlight Java HTTP Server with JWT Authentication, IoC, and Role-Based Access

This project is a lightweight, framework-free RESTful HTTP server built with pure Java. It includes:

• Custom IoC Container (like a mini Spring)
• Lightweight HTTP server using HttpServer
• JWT-based authentication (login & register)
• Role-based access control (ADMIN / USER)
• IP restriction
• Virtual threads for concurrency (Project Loom)
• JSON request/response parsing
• Dispatcher-style handler (like Spring's DispatcherServlet)

---

Features

• Custom dependency injection
• REST endpoints (/register, /login, /tenants, /health)
• JWT Authentication
• Secure endpoints using role-based and IP filtering
• Concurrency with virtual threads
• Fully extendable controller/handler structure
