/**
 * TACO provider — searches the curated subset of the TACO 4 (UNICAMP/NEPA)
 * Brazilian food composition table (curated subset; full ingest planned).
 *
 * Search ranks by:
 *   1. Exact alias match (highest)
 *   2. All query tokens present in name_pt or aliases
 *   3. Partial match (downgraded)
 *
 * Diacritics are normalized so "açai" matches "Açaí" and "feijao" matches
 * "feijão". Each returned FoodItem is auto-enriched with carbon data when
 * a match exists in the carbon dataset.
