feat: add CI workflow for linting, testing, building, and deploying S… #1

	# CI: lint, test, Turbo build; upload Storybook static site; deploy to GitHub Pages (main only).
	#
	# Manual setup (once per repo): Settings → Pages → Build and deployment → Source: GitHub Actions.
	# If prompted, approve the `github-pages` environment for this workflow.
