feat: enhance CI workflows with smoke tests for CLI scaffolding

Added a new smoke test step in the CI workflow to validate the CLI scaffolding process, ensuring that generated projects function correctly. This includes packing the CLI project, installing it as a tool, and running a series of commands to verify the setup. Additionally, enabled automatic deployment of GitHub Pages in the preview workflow to streamline the publishing process.
