A Trakt item only carried its English title, so a Plex or Jellyfin library
filed under the romaji title (`Sousou no Frieren`), the user's language
(`Frieren: Tras finalizar el viaje`) or the native title stayed invisible to
the Explore library lookup.
The Trakt detail load now fetches /aliases and /translations/{app locale}
alongside people and related, picks one ASCII alias from the item's own
country plus the locale translation as alternate titles, and the matcher
reads original_title for every source. The lookup budget grows to four
title families, the matcher keys its cache on the candidate titles, and the
detail screen re-resolves when a detail load adds titles, not only ids.
