feat: Add comprehensive test suite with 46 passing tests
- Add pytest configuration in pyproject.toml with markers and async support - Create shared test fixtures in tests/conftest.py for config, auth, and sample data - Implement unit tests for all major components: * Configuration management (11 tests) - TOML loading/saving, singleton pattern * FastAPI API endpoints (12 tests) - Banks, accounts, transactions with mocks * CLI API client (11 tests) - HTTP client integration and error handling * Background scheduler (12 tests) - APScheduler job management and async ops - Fix GoCardless API authentication mocking by adding token endpoints - Resolve TOML file writing issues (binary vs text mode for tomli_w) - Add comprehensive testing documentation to README - Update code structure documentation to include test organization Testing framework includes: - respx for HTTP request mocking - pytest-asyncio for async test support - pytest-mock for advanced mocking capabilities - requests-mock for CLI HTTP client testing - Realistic test data fixtures for banks, accounts, and transactions 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
