-- Modules: reusable cohesive units (e.g. data_table) versioned with semver.
-- A module groups a set of related registry functions/types under a single
-- versioned artefact that apps opt into via uses_modules in app.md.
--
-- Modules son datos vivos: fn sync los replica entre PCs igual que apps/proposals.
-- Aunque la fuente es modules/*/module.md (parseable), conservamos created_at /
-- updated_at de forma persistente para mantener historico cross-PC.
