Subject: [PATCH] tests: add Python test infrastructure with 30 tests

- Add pytest configuration (pytest.ini)
- Add shared fixtures in conftest.py (temp files, sample data)
- Add test_prodillo_logic.py: winner determination, treasury calc, round state
- Add test_bitcoin_prices.py: price tracking, ATH detection, notifications
- Update .gitignore: exclude __pycache__, .venv, .pytest_cache

All 30 tests passing.
