Mallet v0.1.0: performance, polish, and release

[vdemeester]

Goal

Ship mallet v0.1.0 as a production-quality release — address remaining performance gaps, finalize documentation, and publish binaries.

Performance optimization

• Connection pooling: Reuse Podman HTTP connections across container operations instead of creating new ones per request
• Parallel container cleanup: Clean up containers/pods concurrently instead of sequentially in CleanupAll()
• Volume reuse strategies: Avoid creating new volumes for each task when workspace content can be shared

Testing

• Run all examples with both chisel and mallet — verify identical results
• Cross-platform testing (Linux amd64, arm64 at minimum)
• Load testing: pipeline with 10+ parallel tasks, verify no resource leaks
• Memory profiling: ensure <500MB for typical pipeline execution
• Graceful Ctrl+C handling: verify all containers/pods are cleaned up

Documentation polish

• Add explanatory comments to all example YAML files
• Verify README.md, docs/ARCHITECTURE.md, cmd/mallet/README.md are complete
• Add troubleshooting section for common Podman socket issues

Release automation

• Verify .goreleaser.yaml produces correct multi-binary archives (chisel + mallet)
• Tag v0.1.0 and publish GitHub release
• Verify binaries work on clean systems
• Publish release notes with feature matrix and known limitations

Acceptance Criteria

• All 13+ examples pass with both tools
• Binary sizes: chisel ~29MB, mallet ~15MB
• goreleaser produces release artifacts for linux/amd64, linux/arm64, darwin/amd64, darwin/arm64
• No container/pod/volume leaks after pipeline completion or cancellation
• Startup time <2 seconds
• README has clear installation and getting-started instructions
