feat(ui-lab): add first-run and update scenarios

Add separate UI Lab scenarios for true first-run onboarding and post-update What's New checks. Keep empty-library fixtures reusable across mock data, tagger readiness, worker pause defaults, and launch-time version state so browser verification can exercise the real flows.
