WHY IT NEEDS A POLICY

Why rhid_criar_feriados needs a policy

The name suggests this tool creates holiday entries in the RHiD system. 'Criar' (create) indicates a Write operation. Confidence is low because the description is empty, but the naming pattern is consistent with sibling tools (rhid_atualizar_feriado updates holidays, so rhid_criar_feriados likely creates them). Creating holidays is reversible, so Write is appropriate rather than Destructive.
