feat: add formatted output for Claude Code execution reports (#18)
* feat: add formatted output for Claude Code execution reports - Write turns formatter - Modify GitHub Action to call formatter instead of dumping raw JSON - Add comprehensive unit tests (30 tests) covering all functionality - Add integration test with sample data for output consistency - Support syntax highlighting for multiple content types (JSON, Python, bash, etc.) - Include turn grouping logic and token usage tracking - Provide CLI interface for standalone formatter usage 🤖 Generated with [Claude Code](https://claude.ai/code) Note: seriously I have never written any line of ts code in my life, so please make sure this is fine as I don't give any guarantees Co-Authored-By: Claude <noreply@anthropic.com> * Add fallback --------- Co-authored-by: Claude <noreply@anthropic.com>
