Detailed Description

Singleton utility for managing global GLFW initialization and termination.

GLFWSingleton ensures that the GLFW library is initialized exactly once per process, and is properly terminated when no more windows are in use. This prevents redundant initialization and resource leaks, and provides a safe, centralized mechanism for managing the GLFW global state.

Usage:

Call GLFWSingleton::initialize() before creating any GLFW windows or contexts.
Use mark_window_created() and mark_window_destroyed() to track window lifetimes.
Call GLFWSingleton::terminate() when all windows are destroyed to clean up resources.

This class is not intended to be instantiated; all methods and state are static.
