By owner directive (2026-10-08), all runbook information lives in the
CTXD project mealquest, file RUNBOOKS.MD, never in the repository.
Delete deploy/RUNBOOK.md, whose content is merged into that CTXD file,
and point the comments in deploy/.env.example, deploy/compose.yaml and
deploy/systemd/mealquest-media-backup.sh at RUNBOOKS.MD instead.
