Fix CI test compilation failures

- Add Hashable conformance to Descriptor struct for dictionary key usage
- Add missing imports: ContainerizationError, Crypto, NIOCore
- Fix SHA256Digest type references to SHA256.Digest
- Fix MockRegistryClient Sendable conformance with @unchecked Sendable
- Fix Image.Config/Image.Rootfs references to ImageConfig/Rootfs
- Fix progress handler usage to match ProgressHandler signature
- Fix nil type context annotations for progress parameters
