Assessment: 🟢 APPROVE

This PR vendors updated versions of github.com/moby/moby/api (v1.55.0-rc.1) and github.com/moby/moby/client (v0.5.0-rc.1), introducing the new ImageAttestations API.

No issues found. The new code is well-structured and follows existing conventions:

• image_attestations.go: Correctly uses the established defer ensureReaderClosed(resp) pattern (matching image_inspect.go, image_history.go, etc.), proper API version guard via requiresVersion, context propagation, and error handling throughout.
• image_attestations_opts.go: Clean functional-options pattern consistent with other option types in this package.
• client_interfaces.go: Interface addition matches the concrete implementation's signature exactly.
• attestation.go: New type file (not in diff but vendored correctly).
• vendor.mod / vendor.sum / vendor/modules.txt: Dependency bookkeeping updated consistently.
