Creation of a simple github actions workflow if users want it

[meenu155]

Is your feature request related to a problem? Please describe.
Setting up CI manually after project scaffolding adds extra effort. Users often want a ready-to-use GitHub Actions workflow to run tests automatically.

Describe the solution you'd like
Add an optional flag or prompt (e.g., --with-actions) in the CLI to generate a basic .github/workflows/ci.yml during setup.
The workflow should handle checkout, Node setup, dependency install, and running tests.

Describe alternatives you've considered

Manually creating the workflow

Using third-party templates

Documenting setup steps instead of automating
