Walkthrough

Changes

The change adds create, JSON merge-patch, and delete operations for detached DPUService resources. The repository, SDK, machine-controller interface, SDK adapter, mocks, and lifecycle tests now support these operations.

DPUService lifecycle

Layer / File(s)	Summary
Repository lifecycle operations crates/dpf/src/repository/traits.rs, crates/dpf/src/repository/kube.rs	DpuServiceRepository now creates, patches, and deletes DPUService resources. Creation uses the resource namespace with a default fallback. Kubernetes API errors propagate through DpfError.
SDK service API and lifecycle tests crates/dpf/src/sdk.rs	DpfSdk now creates services in its configured namespace, patches services by name, and deletes services. Mocks and lifecycle tests cover namespace assignment, patch delegation, and deletion.
Machine-controller delegation crates/machine-controller/src/dpf.rs	DpfOperations exposes the new service operations. DpfSdkOps delegates each operation to DpfSdk.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 05081
