#5766 "A root helper the agent can start, for a fixed set of maintenance actions and nothing else", milestone 514. The agent runs unprivileged under NoNewPrivileges, so it can't update or reboot its host. It now leaves a request in /var/lib/steward-agent/requests, the one path its unit lets it write; steward-maint.path starts maint.py as root, which reads it without following links, accepts only update, reboot, drain or undrain, deletes it, and writes the outcome to /var/lib/steward-maint/results. The agent (1.17.0) reports each new result state once as a `maintenance` event, re-checks pending updates when an update finishes, and says in its metadata whether the helper is installed. The units and the helper are served from one copy at /plugins/host_agent/files/<name> (a fixed list), and install.sh plus the install, provision and update playbooks all fetch them, replacing three inline copies of the unit. Update agent installs the helper on existing hosts; the Agent panel says under Manage agent whether it is there. Steward handing out jobs is #5767; the cadence is #5768.
