Subject: [PATCH] fix(wayland): combine GLFW backend check with
 XDG_SESSION_TYPE detection

The previous check using `glfwPlatformSupported` was insufficient as it only tests compilation support, not the active session type. This caused false positives on systems with Wayland-enabled GLFW libraries on X11 sessions.

Now also verify the XDG_SESSION_TYPE environment variable to ensure an actual Wayland session is active, preventing the crash on x11.

Fix: #73
