Add Nicolás Lofredo-Rota as third author

He was part of the informal project team and, per the July 2026
symposium transcript, had the discussions with Salingaros that informed
what to ask the AI for the Ecuadorian Form Language Grammar. Updates the
byline/affiliations, names him in §3.2 where he was previously
anonymized as "a Quito-based designer and self-builder", and
disambiguates the remaining "the authors" references that now need to
distinguish the two-author Track A/B comparison from the full
three-author byline.
