Subject: [PATCH] static-file list: fleet-verified rewrite + root-vs-suffix
 matching

Verified static-file dirs across the reachable fleet via per-host cursor inspection
(de-13/14/16/22/27/30/31/32/35, us-16/41, uk-4). Findings:
- nitro freezers are network-prefixed (arbitrum-one/nitro/l2chaindata/ancient ... up to
  1.3 TB), so the old chain/ and data/ prefixes matched nothing;
- missing: snapshots (erigon3/op-erigon/cosmos), lightchaindata/ancient, nested l2geth
  geth/geth/chaindata/ancient, aztec archiver, nitro classic-msg/ancient;
- bare `ancient` matched nothing (all are nested).

List rewritten to canonical entries. Matching (backup-node.sh manifest + show-static-
file-size.sh) now: entry with NO slash = root-level only (so `snapshots` does NOT catch
postgres pg_logical/snapshots), entry WITH a slash = path-suffix via find -path "*/X"
(matches any prefix: network-prefixed nitro, nested datadirs). The manifest now records
the CONCRETE per-volume path so restore-volumes.sh recreates the exact symlink.
