feat: add comprehensive development infrastructure and CI/CD pipeline

- Add GitHub Actions CI/CD workflow with multi-OS testing (Ubuntu, macOS)
- Add pyproject.toml for modern Python packaging with hatchling
- Add pre-commit hooks for code quality (ruff, mypy, trailing whitespace)
- Add Makefile for common development tasks (install, test, lint, format, build)
- Add run_tests.py script for comprehensive test execution
- Update requirements.txt with development dependencies
- Update .gitignore for modern Python tooling (uv, ruff, pytest)
- Add KiCad-specific ignore patterns for backup files

This establishes a robust development workflow with:
- Automated testing on Python 3.10, 3.11, 3.12
- Code formatting and linting with ruff
- Type checking with mypy
- Coverage reporting with pytest-cov
- Package building with uv
