Consolidate privacy policies per-subdomain:
- Migrate Gaze and Life and Lineage privacy policies verbatim from the
legacy /privacy-policy/* routes to their subdomain paths
(gaze.freno.me/privacy, lineage.freno.me/privacy), and replace the old
routes with 308 permanent redirects to preserve SEO equity and stable
link resolution.
- Add net-new privacy policies for the InputHalo and Nessa subdomains.
- Update the contact page link to point at the Lineage subdomain privacy
policy.
