- Зачем:
  - менти и посетителям сайта нужен быстрый способ связаться с ментором.
- Что:
  - добавлена floating-кнопка Telegram (левый нижний угол, всегда видна при скролле).
  - добавлены иконки Telegram и GitHub в футер через extra.social.
  - создан template override (overrides/main.html) с inline-стилями.
- Проверка:
  - mkdocs build --strict проходит без ошибок.
  - кнопка видна на всех страницах, ведёт на t.me/dementev_dev.
