Resolves GitHub issue #28 by implementing proper layered image building
that preserves base image properties and handles cross-registry scenarios.
Changes:
- Enhanced push_layered_image() to detect cross-registry pushes and copy base layers
- Implemented automatic blob copying from source registry to destination registry
- Always use layered approach instead of falling back to single-layer builds
- Added verification tests to ensure base image environment and files are preserved
- Consolidated unit tests into module files for better organization
This fixes "MANIFEST_BLOB_UNKNOWN" errors when pushing layered images that
reference base image blobs from different registries (e.g., cgr.dev → ttl.sh).

krust builds container images for Rust applications without Docker:
- Builds static binaries using musl libc
- Creates minimal OCI container images
- Pushes to any OCI-compliant registry
- Outputs digest to stdout for composability
Inspired by ko.build for Go applications.
