feat: add Hermes worker anchor and provisioning script for Paperclip employees

- Add x-hermes-worker YAML anchor template in compose.yml
  (CPU-only workers, no GPU passthrough, OpenCode Go provider)
- Add commented worker example with env vars placeholder
- Create scripts/provision-hermes-worker.sh for automated worker
  provisioning (generates port, API key, volume dir, appends service)
- Workers connect to Discord only, isolated per container
- Volumes under /mnt/HoardingCow_docker_data/Hermes/<name>/
