Added width/height tracking to the window class via a GLFW resize callback. The callback stores the current size and forwards it to a user-provided std::function. Added context::set_size() to update the GL viewport when the window is resized. Changed scene::render() to accept (int width, int height) parameters so scenes can compute the correct aspect ratio for their projection matrix instead of hardcoding 1280/720. Fixed parameter shadowing in resize_callback_impl (glfw_window instead of window).
