Replace the vendor/oci-distribution dependency with a custom implementation
that directly follows the OCI Distribution Specification using hyper for HTTP.
Key improvements:
- Direct HTTP implementation using hyper, hyper-util, and hyper-tls
- Support for Bearer token, Basic auth, and Anonymous authentication
- Cross-registry blob copying for layered images
- Multi-platform manifest list support
- Better error handling and redirect support
- Reduced dependency footprint
Technical changes:
- Remove vendor/oci-distribution dependency
- Add hyper ecosystem dependencies for HTTP client
- Implement OCI types: OciDescriptor, OciImageManifest, OciImageIndex
- Add ImageReference parsing with registry/repository/tag/digest support
- Implement registry authentication flows (Bearer token requests)
- Add blob upload/download with redirect handling
- Support manifest pulling with image index resolution
- Fix manifest size validation for Docker compatibility
- Update integration tests to use new registry auth types
- Handle docker.io redirect to registry-1.docker.io correctly
This enables more flexible authentication handling and reduces external
dependencies while maintaining full OCI compliance.

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.
