Update cargo config to use aarch64-linux-gnu-gcc instead of
aarch64-linux-musl-gcc, which matches what's available in CI.
This resolves the "linker not found" error in CI builds.

Remove complex cross-compilation setup that was causing linker
errors. The simplified approach should work with the available
system linkers and musl-tools package.

Restore support for the --image flag that was accidentally removed
in the previous refactoring. This ensures all existing tests and
workflows continue to work while maintaining the digest-only approach.
- Restore image reference parsing with tag/digest stripping
- Maintain backward compatibility with existing CLI interface
- All integration tests now pass

Platform-specific images are now pushed without any tags, only by digest.
This ensures no platform tags like :platform-linux-amd64 are created in
the registry, addressing the core requirement of issue #27.
- Added push_image_by_digest() method to registry client
- Platform images use digest-only references for manifest list
- Only manifest lists can receive explicit tags via --tag flag
- Eliminates all unwanted platform-specific tags from registry

Images are now pushed by digest only by default, with optional tagging
via the new --tag flag. This addresses issue #27 by ensuring:
- No automatic :latest tags are applied during build
- Platform-specific images are never tagged for external use
- Only manifest lists can receive tags when explicitly requested
- Default behavior outputs digest-only references for reproducibility

Remove the custom keychain implementation and keep only the simple wrapper
around oci-distribution's built-in auth. This change:
- Removes 300+ lines of duplicate authentication code
- Leverages well-tested oci-distribution auth functionality
- Simplifies the codebase and reduces maintenance burden
- Maintains full backward compatibility
The custom keychain implementation was never used in production code,
only the simple resolve_auth function was called. All tests have been
updated and are passing.

- Added `use_chunked_uploads` field to ClientConfig (default: true)
- Modified push_blob to respect the chunked upload configuration
- Configured krust to disable chunked uploads for better registry compatibility
- Added comprehensive tests for the new configuration option
This allows callers to control whether chunked/multi-part uploads are used,
which improves compatibility with registries that may not support them well.

- Move Docker config parsing and credential helper execution from krust
- Add automatic auth resolution methods (*_auto) to the client
- Support standard Docker config locations and environment variables
- Add comprehensive tests and examples
- Simplify krust to use the new credential helper functionality
The previous commit added vendor/oci-distribution as a git submodule pointer,
which caused CI to fail because the files weren't actually present.
This commit removes the submodule and adds the actual files directly.
- Fork oci-distribution v0.11.0 into vendor/oci-distribution
- Add get_image_platforms() method for proper platform detection
- Support fetching config blobs for single-platform images
- Add OAuth2/Bearer token authentication support
- Add push_manifest_and_get_digest() for reliable digest extraction
- Update krust to use the forked version with enhanced features
This implements authentication for container registries, porting
functionality from go-containerregistry's authn package to Rust.
Key features:
- AuthConfig struct for various auth types (basic, bearer, anonymous)
- Authenticator trait for pluggable auth providers
- DefaultKeychain that reads Docker config files from standard locations
- Support for credential helpers (docker-credential-*)
- Integration with oci-distribution for registry operations
The implementation checks for credentials in this order:
1. DOCKER_CONFIG environment variable
2. REGISTRY_AUTH_FILE environment variable
3. XDG_RUNTIME_DIR/containers/auth.json
4. HOME/.docker/config.json
Credential helpers are supported if configured in the Docker config.
This enables krust to:
- Pull private base images
- Push to authenticated registries
- Support various auth methods (basic, token, oauth2)

Instead of changing directories, pass the path directly to krust.

- Detect supported platforms by inspecting the base image manifest
- Build for all platforms supported by the base image by default
- Filter out invalid/unknown platforms from manifest
- Normalize platform variants (e.g., linux/arm64/v8 -> linux/arm64)
- Only include platforms that krust supports
- Deduplicate normalized platforms
- Allow explicit --platform to override automatic detection
- Add tests for platform detection functionality
- Add test case for Alpine base image with many platforms
- Update documentation to explain the new behavior
This makes multi-arch builds more intuitive - if your base image supports
multiple platforms, krust will automatically build for all supported ones.

This commit eliminates test flakiness by building to unique temporary
directories and updates the README to reflect all changes in this branch.
Code changes:
- Modified RustBuilder to use tempfile::tempdir() for each build
- Added BuildResult struct to keep temp directory alive during image build
- Each build now gets its own isolated target directory
- Removed clean_example_dir() and all cleanup logic - no longer needed
- Tests can now run concurrently without interfering with each other
Documentation updates:
- Added "Isolated builds" and "Concurrent builds" to key features
- Added comprehensive "Build Process" section explaining the temp directory approach
- Updated multi-arch documentation to reflect default behavior (builds both platforms)
- Added "Multi-Architecture Images" section explaining how multi-arch works
- Documented that manifest list support is planned for future release
Benefits:
- No more "Built binary not found" errors
- Tests run reliably every time
- Concurrent test execution is now safe
- Simpler test code without cleanup logic
- Clear documentation of build isolation
