Hosts like rpc-us-32 put /var/lib/docker (or volumes/) on another mount;
tar -C / then EXDEV on every var/lib/docker/volumes/... member. Canonicalize
the deepest static prefix (readlink -f /var/lib/docker/volumes) and append a
--transform after SLOWDISK_TRANSFORMS. Keying only on /var/lib/docker misses
a real docker root with volumes/ as the symlink. No-op on normal hosts.
Per-volume _data static-file offload stays on SLOWDISK_TRANSFORMS.

The 1MB near-empty guard (added for purged-volume zstd stubs) rejected every
legitimate _config volume archive (cronos: 68KB), so any node whose registry
entry includes a _config volume reported Restorable: 0 despite healthy
multi-GB data backups (cronos had three; 14 registry entries carry _config
volumes). _config archives now pass at >=4KB; data volumes keep the 1MB floor.

select_newest_remote_backup_from_list was sorting an empty process
substitution instead of the piped list-backups.sh output.

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.
