feature(ci): Add Ruff linting configuration and GitHub Actions workflow

- Add Ruff configuration to pyproject.toml with PEP 8 compliance
  - Line length: 88 characters
  - Indentation: 4 spaces (PEP 8 standard)
  - Enable comprehensive rule sets (pycodestyle, pyflakes, isort, pylint, etc.)
- Create .github/workflows/codequality-ruff.yaml
  - Runs on PRs to main and pushes to main/release/* branches
  - Checks both linting and formatting (blocking)
- Fix yamllint errors in config.yaml and release workflow
- Remove whitespace from table_display.py
