Detect the terminal background (via COLORFGBG or an OSC 11 query) before GUI init and, on the first start, automatically apply the built-in "light" theme when a light terminal is detected. The function gui_term_theme_is_light returns an int (1 if light, 0 otherwise, 0 being the safe value when detection is unsure).
