Detailed Description

Awaitable stream of GLFW window input events.

Signals are produced by GLFW callbacks on the main thread. Coroutines suspend via WindowEventAwaiter and are resumed synchronously from signal(). Tracks input state for immediate polling via is_key_pressed(), is_mouse_pressed(), and get_mouse_position().
