Tripuck eSIM search — prepaid travel data plans (eSIM) for a destination country, compared across multiple providers. Use this when the user asks about mobile data, internet, SIM or eSIM for a trip, e.g. "eSIM for Japan", "data plan for my trip to the US", "internet in Dubai", "Japonya için eSIM", "خطة بيانات لدبي", "Datentarif für die Türkei". Input: a destination country (the LLM maps the place to its ISO country code), with optional minimum data (GB), validity days and sorting. Returns available packages with data amount, validity, coverage and price, each deep-linking to Tripuck.com for purchase. The LLM MUST infer the user language from the conversation and pass it via the `locale` parameter ("tr" Turkish, "en" English, "ar" Arabic, "az" Azerbaijani, "de" German, "ka" Georgian, "uz" Uzbek). All widget UI text and the text response are then returned in that language. If `currency` is not specified, a sensible default is picked from the locale (tr→TRY, en→USD, de→EUR, ar→USD, az→AZN, ka→GEL, uz→UZS).
