One-liner instead of "ssh + heredoc + sudo + sh -c + double quotes":
sudo left4me create-user alice --admin
sudo left4me seed-script-overlays /opt/left4me/src/examples/script-overlays
sudo left4me routes
The wrapper sources host.env + web.env, drops to the left4me user,
sets JOB_WORKER_ENABLED=false (admin-side ops shouldn't race the
worker) and PYTHONPATH=/opt/left4me/src, then exec's the flask CLI
with whatever args followed `left4me`. No env-var enumeration: the
sh -c trailing 'sh "$@"' forwards positional args without quoting
hell. README updated to drop the verbose recipe.
