- 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.

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

- Updated get_test_platform() to detect runtime architecture in CI
- CI tests use native platform (linux/amd64 on x86_64, linux/arm64 on aarch64)
- Local development always uses linux/amd64 for consistency
- Added test_multi_arch_build_and_run() test
- Builds multi-arch image and pushes to ttl.sh
- Verifies the image runs correctly on the current architecture
- Gracefully handles missing toolchain scenarios
- Updated CI integration test to verify multi-arch images can run
- Builds for both linux/amd64 and linux/arm64
- Runs the image to ensure Docker selects the correct architecture
This ensures we properly test both single and multi-arch scenarios.

This commit fixes CI failures by:
1. Added cargo config setup to all test jobs:
- Ensures correct linkers are configured before running tests
- Uses x86_64-linux-musl-gcc for x86_64 targets
- Uses aarch64-linux-gnu-gcc for ARM64 targets
2. Updated tests to handle cross-compilation gracefully:
- Single-platform tests always use linux/amd64
- Multi-platform tests attempt to build for both architectures
- Tests verify the appropriate error messages if targets are missing
- No tests are skipped - they either pass or fail with expected errors
3. Enhanced CI verification:
- Added verification of aarch64-linux-gnu-gcc availability
- Shows the cargo config being used
This ensures tests run consistently across all environments without skipping.

- Support building for multiple platforms with --platform flag
- Accept comma-separated platforms or multiple --platform flags
- Default to building for linux/amd64 and linux/arm64
- Add ARM runner (ubuntu-24.04-arm) to CI matrix
- Create manifest list for multi-arch images (TODO: push to registry)
- Update integration tests to handle multi-platform builds
- Add cross-compilation setup instructions to README
- Add .cargo/config.toml for local development
Breaking changes:
- Default behavior now builds for multiple platforms (amd64+arm64)
- Use --platform linux/amd64 to build for single platform
Remove Windows from the CI matrix to focus on getting Linux and macOS
working reliably first. Windows cross-compilation and Docker support
can be added back once the core functionality is stable.
- Use docker/setup-buildx-action for consistent Docker setup across all platforms
- Fix Windows rust-lld configuration by using full path instead of command name
- Make Docker-dependent tests fail explicitly when Docker is not available
- Add proper Docker availability check in integration tests

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.
