 * `cleo backup verify` core SDK — per-DB freshness + integrity walker.
 *
 * Walks every entry in `DB_INVENTORY` (`@cleocode/contracts`) and reports
 * the freshest snapshot in BOTH the canonical backup directory
 * (`.cleo/backups/sqlite/` per T10315 / ADR-013 §10) and the legacy backup
 * directory (`.cleo/backups/snapshot/`, retained read-only for one
 * deprecation window). Each freshest snapshot is opened via
 * {@link openCleoDbSnapshot} (the canonical chokepoint, allowlisted under
 * `packages/core/src/store/**`) and verified with `PRAGMA integrity_check`.
 *
 * Verdict semantics live in {@link BackupVerifyVerdict}; the CLI verb's exit
 * code is driven directly by the `summary` returned here.
