Los archivos .go de tipos ahora viven junto a las funciones en functions/{domain}/
(mismo paquete Go), resolviendo errores de compilación por tipos no encontrados
(Option, Pair, Result, etc.). Los .md de metadata permanecen en types/{domain}/
con file_path actualizado a functions/. Se elimina types.go duplicado de infra.
