- 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.

- 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.

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.
