Related to rustfs/backlog#2688.
## Summary of Changes
Reclaim metadata-less orphan directory trees after a complete, first-page, empty recursive root listing in an authoritative never-versioned bucket. Both listing implementations use the same fail-closed cleanup decision.
## Verification
Head b4a9120173 received an approval from loverustfs in review 5365460152. This merge does not add a local runtime validation claim. Full main CI remains a separate publication gate.
## Impact
Empty recursive root listings can remove otherwise unaddressable physical residue. Versioned buckets and populated listings remain excluded; unreadable disks, object metadata, unknown files, and uncommitted data prevent cleanup.
## Additional Notes
Reverting this change restores the previous orphan-directory behavior.
