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.

- These methods automatically resolve auth from Docker config and credential helpers
- Update example to demonstrate both explicit and auto auth approaches
- Simplify krust's auth wrapper to use the new convenience method
- Fix test environment variable pollution
