chore: rebrand farhoodliquor → farhoodlabs, API-only mode, split infra

- Rename org references from farhoodliquor to farhoodlabs in CI workflows
  and GHCR image tags
- Rewrite README for Hightower as API-driven K8s fork of Shannon
- Update CLAUDE.md to reflect API-only deployment model
- Delete docker-compose files (K8s only, no Docker Compose support)
- Delete shannon CLI entry point (API-only going forward)
- Move K8s manifests to farhoodlabs/hightower-infra
