backup-node.sh now stops services, fences COMPOSE_FILE during backup, and
restores via EXIT trap; consumers skip <1MB .tar.zst artifacts so purged-
volume junk cannot shadow real backups.

restore-volumes.sh: pre-create static-file symlinks from the backup's .txt manifest so
the immutable ancient/freezer dirs land on /slowdisk (SSD) and extract THROUGH the
symlinks via tar --keep-directory-symlink (was --dereference, which clobbered them);
hot state stays on the primary disk. Cleans stale /slowdisk targets first (no leak on
re-restore). Safe fallbacks: no /slowdisk / no manifest / no static paths -> normal
extract. Reth excluded (reth dropped whole-dir static-file symlinks).
volume-utils.sh: add delete_slowdisk_targets_for_key() — follows a volume's symlinks and
sweeps the rpc_<key>__data_ pattern under /slowdisk (matches delete-volumes.sh).
cleanup-volumes.sh: free the /slowdisk static data before docker volume rm (was leaking),
and fix the fragile substring used/unused match to an exact name match.
