Joan Marc Riera dfdc499d5d feat(website): publish Privacy, Terms, and Google Limited-Use legal pages
Self-authored legal docs for Castellum, published under the personal brand at
castellummail.com/{privacy,terms,google-limited-use} to support Google OAuth
verification (no attorney, per project decision). Reflects local-first default
with an optional, opt-in, off-by-default cloud-AI mode. Footer links added.
