feat(igdb): oyun aramasına yıl filtreleme desteği ekle

Oyun adında yıl belirtilirse (örneğin "Ghost Town 2025"),
bu bilgiden yararlanarak IGDB'den doğru oyunu bulmak için
yıl filtreleme özelliği eklendi.

extract_year_from_name ve remove_year_from_name fonksiyonları
eklendi. Yıl belirtilmişse daha fazla sonuç getirilip
yıl aralığına göre en uygun oyun seçiliyor.
