Mexico TIGIE Engine (Real SIICEX Data)

completedcode_genP1

Description

Build rosetta_core/mx_tariff.py — Mexico tariff engine using real TIGIE data. Currently Mexico uses HS-6 pivot only (no real MX API call in multi_jurisdiction.py). Mexico uses 8-digit fracciones arancelarias. Data source: SIICEX-CAAAREM (siicex-caaarem.org.mx) or SAT LIGIE tables. Must handle: fraccion arancelaria lookup, IGI (Impuesto General de Importación) rates, IVA (16%), IEPS where applicable, USMCA/CPTPP preferential rates, NOM (Normas Oficiales Mexicanas) flags. Architecture: mirror uk_tariff.py. Add real MX dispatcher to multi_jurisdiction.py. Critical: Mexico is home market + USMCA corridor. Tests required.
