The cargo-zigbuild cache was shared between x86 and ARM runners
(cache key only used runner.os), causing "Exec format error" when
an ARM binary was restored on x86 or vice versa. Added runner.arch
to all cache keys and use --force install to overwrite stale binaries.

cargo-zigbuild --version doesn't work reliably in all PATH configs.
Use cargo zigbuild --help instead, which uses cargo's subcommand
discovery to find the cargo-zigbuild binary. Also verify zigbuild
actually works in CI after installation.

Integration tests now skip instead of panicking when Docker or
cargo-zigbuild aren't available. Also removed redundant make test-e2e
step from CI since make test already includes e2e tests.

- Make zigbuild a hard requirement instead of optional with fallback
- Remove configure_cross_linker and all system linker detection logic
- Remove apt-get install of system cross-linkers from CI
- Remove unused `which` dependency
- Fail fast with clear install instructions if zigbuild is missing
https://claude.ai/code/session_01EcsZDNeWn56wFqryb4Wq7r
The snap install was unreliable and the apt fallback used a
non-existent package name. pip install ziglang is the recommended
way to install zig in CI environments.

- Integrate cargo-zigbuild as the default build backend, falling back
to cargo build with best-effort linker detection if not installed
- Auto-install rustup targets when missing (rustup target add)
- Use persistent target/krust/ directory instead of temp dirs so
incremental compilation works across runs
- Remove .cargo/config.toml from repo (add to .gitignore) since
zigbuild handles cross-linker configuration
- Improve error messages: suggest cargo-zigbuild when linker not found
- Simplify CI to use zigbuild instead of per-target system linkers
- Simplify Makefile by removing setup-cross-compile/verify targets
- Update README and CLAUDE.md to reflect new approach

- Only run make run-built-image on ubuntu-latest (x86_64) runners
- ARM64 runners cannot cross-compile for x86_64 due to linker architecture mismatch
- Prevents 'file in wrong format' errors when ARM64 musl-gcc tries to link x86_64 objects

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

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

Instead of changing directories, pass the path directly to krust.
This ensures the command runs from the correct working directory
where the krust binary is located.

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
