fix: cover image variety — concrete metaphors + articleId cycling

Browse Source 
getVisualMetaphor():
- articleId % array.length как чистый индекс цикличности
- Метафоры конкретные/материальные (ключи, телескопы, часы, книги)
  вместо абстрактных neural nodes которые все выглядят одинаково
- AI категория: 14 метафор (повтор через 14 статей = ~5 дней)
- 11 тематических категорий + 15 универсальных
