Add deploy/ unit files for every DECNET daemon (agent, updater, api, web, swarmctl, listener, forwarder). All run as User=decnet with NoNewPrivileges, ProtectSystem, PrivateTmp, LockPersonality; AmbientCapabilities=CAP_NET_ADMIN CAP_NET_RAW only on the agent (MACVLAN/scapy). Existing api/web units migrated to /opt/decnet layout and the same hardening stanza. Make the updater's _spawn_agent systemd-aware: under systemd (detected via INVOCATION_ID + systemctl on PATH), `systemctl restart decnet-agent.service` replaces the Popen path so the new agent inherits the unit's ambient caps instead of the updater's empty set. _stop_agent becomes a no-op in that mode to avoid racing systemctl's own stop phase. Tests cover the dispatcher branch selection, MainPID parsing, and the systemd no-op stop.
