The folder kept its name from before the monorepo (ADR 0015), though
Train and Todo deploy from it too. redeploy.sh, the backup's units and
the operator's steps name ~deploy/halkyon; the Compose project keeps the
name halkyon-learn, as Docker names its volumes after it.

The server moves after this is deployed: the running redeploy.sh is read
whole before it runs, so the deploy of this commit still works in the
old folder; then the folder is moved, the pinned commands in deploy's
authorized_keys and the backup's units changed, and the containers
recreated on the new paths.
