Onboarding can be skipped and revisited later

Mandatory onboarding that cannot be skipped traps users who already know the product, already have an account elsewhere, or simply want to look around first. The user-experience taxon treats skippability as a respect-for-user-autonomy issue: forcing every new user through a linear wizard raises bounce rates among exactly the high-intent users who would otherwise activate quickly. Equally, onboarding that disappears forever once completed or skipped gives users no way to rediscover features they missed, turning onboarding into a one-shot tutorial instead of a persistent reference.

Add a "Skip for now" action to every onboarding step and expose onboarding as a persistent "Setup guide" entry in the navigation so users can return. In src/app/(app)/onboarding/[step]/page.tsx render a secondary Skip button alongside Continue, and add a navigation link in src/components/Sidebar.tsx.

<div className="flex justify-between mt-8">
  <Button onClick={handleNext}>Continue</Button>
  <Button variant="ghost" onClick={() => router.push('/dashboard')}>Skip for now</Button>
</div>
