Add comprehensive test suite with runtime-generated secrets

- 70+ tests covering regex-based sanitization - API keys: OpenAI, Anthropic, GitHub, HuggingFace, Stripe, SendGrid, Google, AWS - Crypto: Private keys, ETH/BTC addresses, seed phrases - Financial: Credit cards, SSN - PII: Email addresses - Context preservation tests - Edge cases and JSONL processing Security: All test secrets generated at runtime to avoid GitHub secret scanning - No hardcoded secrets in test files - Uses random generators for realistic test patterns - Follows security best practices CI: GitHub Actions workflow for multi-OS/Python testing with coverage
