v1.2.0 — RankMath dual-type schema fix
Adds FIX #3: collapses RankMath's dual-typed Organization/LocalBusiness node to its LocalBusiness subtype so priceRange/openingHours validate (fixes SEMRush 'property not recognized by Organization'). Head-only JSON-LD filter; only touches nodes that are both Organization and a LocalBusiness subtype.
