Add pre-commit configuration and CI workflow

- Add .pre-commit-config.yaml with hooks for ruff, black, codespell, and whitelist validation
- Add GitHub Actions workflow for pre-commit CI on pull requests
- Add pre-commit to dev dependencies in pyproject.toml
- Fix ruff configuration by removing invalid 'concise' output format
- Update codespell ignore list to handle existing spelling issues in icon data

The pre-commit configuration reuses existing tool configurations:
- Ruff settings from pyproject.toml
- Codespell settings from .codespellrc
- Black version matches project dependencies
- Whitelist validation uses same logic as existing CI
