* feat(issue-17): add onboarding wizard for new users

Adds a step-based onboarding wizard that guides new users through their
first Claw3D setup: welcome, prerequisites, gateway connection, agent
discovery, and a completion screen.

Architecture:

src/features/onboarding/ (new feature module):
  - types.ts: Step definitions, navigation helpers (getNextStep/getPrevStep)
  - useOnboardingState.ts: localStorage-backed persistence hook
  - index.ts: Barrel exports for clean imports
  - components/OnboardingWizard.tsx: Main wizard container with step
    navigation, progress bar, and modal overlay
  - components/WelcomeStep.tsx: Feature highlights grid
  - components/PrerequisitesStep.tsx: Checklist with links/commands
  - components/ConnectStep.tsx: Compact gateway connection form
  - components/AgentsStep.tsx: Agent discovery feedback
  - components/CompleteStep.tsx: Final screen with CTA

Design decisions:
  - Modular step system: new steps can be added by extending
    OnboardingStepId and registering a component in the switch
  - localStorage persistence: wizard shows once per browser, resettable
    from settings (future: wire into Studio settings API)
  - Connect step gates forward navigation: users cannot skip connection
  - Follows Claw3D conventions: feature-first module, no shared state
    pollution, Tailwind utility classes, lucide-react icons
  - Does NOT modify existing routes or components — zero-risk integration
    (parent wiring left to maintainer preference)

Integration guide (for maintainer):
  1. Import { OnboardingWizard, useOnboardingState } from the module
  2. Add useOnboardingState() to the root layout or agents page
  3. Render <OnboardingWizard /> when showOnboarding is true
  4. Pass gateway connection props from existing store

tests/unit/onboardingTypes.test.ts (13 tests):
  - Step structure validation, navigation helpers, ordering

tests/unit/onboardingState.test.ts (5 tests):
  - localStorage persistence, show/hide/reset lifecycle

Addresses #17

* fix(onboarding): wire wizard launch into office UI

Mount the onboarding wizard in OfficeScreen and add a settings action that can re-open it so the new-user flow is reachable and testable.
