ruc_ec_natural_validate $0.001 per call

Offline validator for an Ecuadorian RUC (Registro Único de Contribuyentes) belonging to a natural person: checks the 13-digit structure, verifies the embedded 10-digit cédula via its modulus-10 check-digit algorithm, confirms the third digit denotes a natural person (0-5), and requires the establishment suffix to be '001'. Pure computation, no network calls.
