feat(inventor): Implement Automated Testing with pytest

Implement pytest-based tests for each exercise in the repository. Each exercise should have a corresponding test file (e.g., `exercise1.py` should have `test_exercise1.py`). The tests should cover various input scenarios and edge cases to ensure the solutions are robust. Implementation approach: * Install pytest. * Create a `test` directory at the root of the repository. * For each exercise file, create a corresponding test file in the `test` directory. * Write test functions using pytest's `assert` statements to validate the exercise solutions. * Add a `pytest.ini` file to configure pytest (e.g., to specify the test directory). Validation results: ⚠️ - Tests: ❌ - Linting: ❌ - Type checking: ❌ 🤖 Generated with [Inventor Agent](https://opentrace.com)
