feat(marketing): refine homepage storytelling and visuals

[NicholasKissel]

Summary

• add the interactive agent stack story and refine homepage section ordering
• replace the hero announcement pill with a dismissible latest-update preview
• simplify the deployment story while retaining Postgres, FoundationDB, and tiered storage to S3
• refresh product motifs, observability framing, integrations, hosting, and reveal behavior

Validation

• browser QA at desktop and mobile sizes for the hero, stack, and deployment diagram
• git diff --check
• Astro server and client production bundles compile; local static generation stops because the prebuild-generated docs collection is absent in this workspace
