infra: full IaC state after hf-pdocker-01 rebuild (2026-03-08)

Replaces initial Nomad/Consul/Terraform skeleton with current Docker-based
infrastructure across all three nodes (hf-pdocker-01, hf-pdocker-02, bart).

Key changes:
- CLAUDE.md: updated service distribution reflecting hf-pdocker-01 restored
- docs/plans/2026-03-08-hf-pdocker-01-rebuild.md: new rebuild plan doc
- compose/bart/: ai-agents, guacamole, matrix, media, openvas, smarthome, watchtower
- compose/hf-pdocker-02/: traefik, monitoring, adguard, gitea, semaphore, wikijs,
  unifi, vaultwarden, actual-budget, mcpo, netclaw, trivy, watchtower, n8n
- compose/hf-pdocker-01/: frigate, frigate-notify, farm-agent
- stacks/: all Swarm stack definitions (monitoring, traefik, smarthome, matrix,
  guacamole, media, ai-agents, frigate, gitea, semaphore, wikijs, unifi, etc.)
- .gitignore: exclude .env credential files and acme.json certs
- .env.example: placeholder credential files for all services
- .claude/agents/: gitea-backup and other infrastructure agent configs
- scripts/: frigate media cleanup and NAS sync scripts
