Two initial Fornax distributed torrent workers, each a gluetun+qBittorrent+natpmpc-helper
pod on a different ProtonVPN TX server with NAT-PMP enabled. VPN private keys stored in
Vault at secret/fornax/worker-tx253 and secret/fornax/worker-tx34, surfaced via
ExternalSecrets. Workers share the media-data PVC; each has its own config PVC.
Services: fornax-worker-tx253:8080 and fornax-worker-tx34:8080 (ClusterIP, media ns)
