Description

Add pre-commit configuration with TOML support and GitHub Actions workflow to improve code quality and consistency.

Changes

• Add pre-commit configuration with the following hooks:
  • Basic TOML syntax checking via pre-commit-hooks
  • TOML sorting via toml-sort
  • TOML formatting and linting via taplo
  • Existing Python linting via ruff
  • JSON and YAML formatting via prettier
• Add GitHub Actions workflow to:
  • Run pre-commit checks on all PRs and pushes to main
  • Automatically commit any formatting fixes
  • Use Python 3.12 for consistency with the project

Testing

• Validated TOML syntax of existing pyproject.toml file
• Pre-commit configuration has been validated for syntax

Notes

This PR introduces pre-commit hooks and automated checks to ensure consistent formatting and valid syntax across the codebase. After merging, developers will need to:

1. Install pre-commit: pip install pre-commit
2. Set up the hooks: pre-commit install

The GitHub Actions workflow will automatically run these checks on all PRs and can automatically fix and commit any formatting issues it finds.
