fix: классификатор не ловил кириллицу и склонения

- regex `\b` в JS не работает с кириллицей (русские буквы не word-char),
  поэтому ни одно русское ключевое слово не давало хитов;
- exact-match не учитывал склонения: «приложение» vs «приложении».

Заменил на ручной матч с допуском в 2 символа суффикса
(shared prefix ≥ max(keyword.length - 2, 4)). Сохранён exact-match
для коротких ключей (sms/ios/crm) чтобы избежать ложных срабатываний.
