Subject: [PATCH] Prevent split-screen join when game window is not focused

Add g_KBMInput.IsWindowFocused() guard to the tryJoin condition so that gamepad input from background windows does not accidentally trigger a split-screen player join. This avoids phantom joins when the user is interacting with another application.
