feat: добавить лоадеры Dots, Rotating Text и DNA Strain

— Добавлен dots-pulsating (минимализм на CSS-переменных) — Добавлен rotating-text (эффект переворота букв с использованием JS) — Добавлен dna-strain (научная анимация цепочки ДНК) — Обновлен общий README.md: коллекция расширена до 8 элементов
