fix(ci): add tests directory and resolve Flake8 errors

This commit resolves the remaining CI/CD failures:

- **Tests Directory**: Removed tests/ from .gitignore and added all test files
  - Added 79 unit tests (test_helpers.py, test_naming.py)
  - Added test configuration (conftest.py, pytest.ini)
  - Tests now properly discovered and run on CI

- **Flake8 Configuration**: Created .flake8 config file
  - Set max-line-length to 120
  - Ignore style conflicts with Black (E203, W503)
  - Ignore intentional bare excepts (E722)
  - Per-file exceptions for import patterns

- **Code Cleanup**:
  - Removed unused imports with autoflake
  - Fixed E713: Changed "not in" syntax in downloader.py
  - Split long line in commands.py (E501)
  - Removed unused variables

All tests pass locally. Flake8 passes with 0 errors.
