Pull Request Overview

This PR switches the project from using multiple formatting tools (yapf, isort, flake8) to using ruff as a unified formatter and linter. The change consolidates the development dependencies and updates the GitHub Actions workflow to use ruff's formatting capabilities.

• Removes yapf, isort, and flake8 from dependencies and replaces with ruff-only formatting
• Configures ruff with specific formatting options (double quotes, space indentation)
• Updates GitHub Actions workflow to use ruff format --check instead of separate yapf and isort checks
