Añade campos params y output al frontmatter YAML de las 506 funciones del registry. Cada parámetro tiene descripción semántica (qué representa, unidades, rango típico) y cada función describe qué produce su output. Permite a agentes razonar sobre cadenas de composición (ej: prices → log_return → sharpe_ratio) sin leer código.
