⏺ Продолжаю с Фазы 8: Cairo/Pango стратегия.                                    
                                                                                
  Согласно плану, Cairo+Pango+glib слишком велики для бандлинга (~1M строк).    
  Нужно:                                                                        
  1. Оставить как системные зависимости                                         
  2. Добавить режим USE_CAIRO=0 для чистого Xlib+Xft рендеринга                 
  3. Задокументировать зависимости
