Get 14-day weather forecast

City name as a human types it, e.g. "Luçon", "Oakland", "Marina di Andora". Resolved via meteoblue's own location search (first/best match, ranked by relevance).

Optional ISO date (YYYY-MM-DD). When given, `days` contains only that day — empty array if the date is outside the 14-day window (not an error).

One entry per forecast day (14 unless filtered by the date arg; empty if date out of window)
