ci: add GitHub Actions workflows for testing, building, and publishing

- Add test workflow to run tests on multiple Node.js versions
- Add build workflow to verify project builds correctly
- Add code quality workflow to check formatting, linting, and type checking
- Add publish workflow to automatically publish to npm on version tags

These workflows will ensure code quality and proper deployment automation.
