- setup remote-services subcommand: enables (default) or removes
(--remove) the remote_services SSH-enablement marker via SSH, targeting
persistent locations (/etc or /mnt/nv) before the volatile /tmp fallback
- setup plan now includes a "persist remote_services" step when the marker
is only in /tmp (would be lost on next reboot, breaking SSH mid-migration)
- setup plan state header shows a [⚠] line when remote_services is
enabled but not persistent
