Static-file offload gating, clearer semantics:
- NO_SLOWDISK defaults to TRUE (offload OFF) — safe default everywhere.
- A host with a real dedicated extra disk at /slowdisk sets NO_SLOWDISK=false in its .env
to ENABLE the offload.
- New --no-slowdisk CLI flag forces NO_SLOWDISK=true, overriding the .env false — for when
the extra disk exists but is full. Flag is parsed position-independently; the positional
args ($1 compose, $2 remote source) are preserved.
Offload runs only when NO_SLOWDISK is false AND the flag was not passed.

A `/slowdisk` directory exists on hosts even when it is just a folder on the root disk
(no dedicated extra disk) — offloading there gives no benefit. Source the host .env and
require SLOWDISK to be set (operator sets it only on hosts with a real extra disk mounted
at /slowdisk) before activating the static-file -> /slowdisk symlink offload. Unset =
normal extract everywhere. Target path stays /slowdisk (the fixed in-container mount).

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.
