* feat(onboarding): add full-screen onboarding wizard for new workspaces
Replace auto-provisioned workspace with an interactive 4-step onboarding
wizard: Create Workspace → Connect Runtime → Create Agent → Get Started.
- Remove server-side ensureUserWorkspace() so new users land in onboarding
- Add onboarding wizard in packages/views/onboarding/ (4 steps)
- Wire login/OAuth callbacks to redirect to /onboarding when no workspace
- Add DashboardGuard onboardingPath fallback for workspace-less users
- Sidebar "Create workspace" navigates to /onboarding instead of modal
- Remove CreateWorkspaceModal (replaced by wizard step 1)
- Auto-generate workspace slug from name (no user-facing URL field)
- Unified CLI install flow: install.sh + multica setup (auto-detects local)
- Create onboarding issues on completion with interactive "Say hello" task
* test(auth): update workspace tests to match onboarding flow
Login no longer auto-creates workspaces — new users start with zero
workspaces and create one through the onboarding wizard. Update both
integration and handler tests to assert 0 workspaces after verify-code.
Desktop Google login flow: click "Continue with Google" → opens default
browser to web login page with platform=desktop → Google OAuth completes
→ web callback redirects to multica://auth/callback?token=<jwt> →
Electron receives deep link, extracts token, completes login.
Changes:
- Register `multica://` protocol in Electron (main process + builder)
- Add single-instance lock with deep link forwarding (macOS + Win/Linux)
- Expose `desktopAPI.onAuthToken` and `openExternal` via preload IPC
- Add `loginWithToken(token)` to core auth store
- Pass `state=platform:desktop` through Google OAuth flow
- Web callback detects desktop state and redirects via deep link
- Desktop renderer listens for auth token and hydrates session
- staleTime: 0 on fetchQuery after leave/delete so fresh data is fetched
- setQueryData before switchWorkspace in createWorkspace so sidebar is
consistent on first render
- seed workspaceKeys.list() cache in login, Google callback, and
settings save so the first useQuery(workspaceListOptions()) hit is free
- remove dead onError from WorkspaceStoreOptions (used only by the
deleted refreshWorkspaces action)

The callback page was placed under app/(auth)/callback/ — a Next.js
route group — which mapped to /callback instead of /auth/callback.
Move it to app/auth/callback/ so the URL matches the Google OAuth
redirect URI.
