rename_profile removed the launchd/systemd unit only when the gateway
was running, and never touched the s6 slot. A unit installed under the
old name but stopped stayed behind: it runs --profile <old> with
HERMES_HOME pinned to the moved directory, so the next login or
container boot crash-looped it for a profile that no longer exists,
and deleting the renamed profile never found it.
The old unit is now removed whether or not the gateway runs, the s6
slot moves to the new name, and the command prints how to reinstall
the service under the new name.
