v0.1.0 - Initial Production Release of Loop Engine Core

🚀 What's New in v0.1.0

Highlights

• Hybrid Polyglot Engine: Go Control Plane & Sandbox Substrate + Python Reasoning Engine.
• 4-Layer Security & Kernel Sandbox:
  • Layer 1: AST Static Analysis preventing sandbox escapes (__subclasses__, getattr, eval/exec).
  • Layer 2: Path Jail Confinement preventing traversal attacks (../../).
  • Layer 3: Kernel Sandbox with POSIX resource limits (ulimit -n 1024, ulimit -t) and OS Process Group (setpgid) subtree termination.
  • Layer 4: Deterministic Circuit Breakers & Token Budget ceilings.
• Universal Project Adapter: Support for C++, Go, Python, Rust, and TypeScript via Loopfile.yaml.
• Maker / Checker Pair Programming: Decoupled generation (Driver) from grading (Navigator/Judge).
• Transactional Workspace Patcher: Automatic pre-loop file snapshotting with instant rollback on task abort.
• Pluggable LLM Driver: Support for local Ollama (qwen2.5-coder, dolphin-llama3), Cloud Frontier models, and offline test fallbacks.
• Continuous Integration: 100% automated test coverage in Go and Python on GitHub Actions.
