Changes PUBLIC URLs — anything linking to the old slugs (external sites, saved
bookmarks, search engines) will 404 unless you opt into alias redirects.

 - generateAlias=false (default): only updates the 'enlace' column. Old URLs
   return 404.
 - generateAlias=true: also writes entries into 'alias_urls' so old URLs
   redirect to the new ones. Safer choice when the table is already public.
