🎉 Initial commit: project scaffold, agent modes, and gnarly_csv example

- Add .roomodes with four custom Roo agents:
    • excalidraw-to-python  – diagram → typed Python skeleton
    • python-coder          – skeleton → production implementation (design patterns)
    • tester                – pytest suite writer & runner
    • orchestrator          – coordinates the full excalidraw→code→test→execute pipeline
- Add src/csv_grok.py and tests/test_csv_grok.py (CSV diff utility)
- Add examples/gnarly_csv/ with gnarly_csv_delta.py and sample data (rev_a/rev_b)
- Add drawings/ with design.excalidraw and gnarly_csv_files.excalidraw
- Add docs/excalidraw-to-python-agent.md
- Add requirements.txt and .gitignore
