RenameNode was calling Resolve() which generated blob keys for directories that don't have blobs, causing 'key not found' errors. Added ResolveRenameOp to BlobKeyResolver interface: - FlatKeyResolver returns nil (UUIDs don't change on rename) - HierarchicalKeyResolver returns move op for files and directories This allows directory renames to work correctly with flat storage, and leverages os.Rename for atomic directory moves with hierarchical.
