refactor: remove emojis and apply code formatting

- Remove all emoji characters from output strings for better compatibility
- Update all tests to match non-emoji output
- Apply black formatting to all Python files
- Ensure all tests pass and linting succeeds
- Remove htmlcov directory (already in .gitignore)

This change improves cross-platform compatibility and ensures
consistent code formatting across the project.
