Subject: [PATCH] Add GitHub Actions CI workflow configuration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add comprehensive CI workflow file for GitHub Actions:
- Test across multiple GHC versions (9.4.7, 9.6.3, 9.8.1, 9.10.1)
- Both Cabal and Stack build configurations
- Run test suite
- Generate Haddock documentation
- Cache dependencies for faster builds

Note: Move this file to .github/workflows/ci.yml to activate.
