- 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
- 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)

- Add support for linux/386 (i686-unknown-linux-musl)
- Add support for linux/arm/v6 (arm-unknown-linux-musleabihf)
- Add support for linux/ppc64le (powerpc64le-unknown-linux-musl)
- Add support for linux/s390x (s390x-unknown-linux-musl)
- Add support for linux/riscv64 (riscv64gc-unknown-linux-musl)
- Update platform detection to include all new platforms
- Add tests for all new platform mappings
- Update documentation with installation instructions for all targets
- Add CI job to test extended platform support
- Update development setup docs to mention cargo-zigbuild for full platform support
This allows krust to build images for all platforms supported by Alpine Linux,
making it more versatile for multi-architecture container deployments.

- 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.

- Always push OCI image indexes (manifest lists) even for single platform builds
- Fix manifest size calculation to use actual pushed manifest size
- Update platform-specific image tagging to use consistent format
- Fix ARM64 linker configuration to use musl toolchain
- Update README to document that manifest lists are always created
- Fix test to use native platform for Docker compatibility
This ensures krust provides a consistent interface regardless of the number of
platforms being built, making it easier for downstream tools to consume images.

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

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.
