- startall now uses systemctl start (not enable --now)
- stopall now uses systemctl stop (not disable --now)
- add installall command (bulk install with --dry-run support)
- add uninstallall command (bulk disable+remove in reverse order)
- fix docker ExecStart to use -a flag so the process stays attached
- prefix ExecStop with - so a stop-on-already-dead container does not fail the unit
