Operator-facing docs must show the short host commands, not the long
docker-compose invocation (same convention already enforced for the in-panel
help/versions/MOTD surfaces):
- Updating: `sudo ./update.sh` -> `sudo clusev update`.
- Recovery: `docker compose -f docker-compose.prod.yml exec app php artisan
clusev:reset-admin` -> `clusev reset-admin`.
Add README.md to CommandShortcutsTest's DISPLAY_SURFACES and
UPDATE_COMMAND_SURFACES so the README is regression-guarded too.
