- Extend auth status API typing to include optional ghCli availability/authentication metadata.
- Update /api/auth/status to return ghCli readiness using isGhAvailable() and isGhAuthenticated().
- Treat setup GitHub readiness as satisfied when either GitHub OAuth or authenticated gh CLI is present.
- Add hook tests covering gh CLI authenticated, unauthenticated, combined OAuth, and missing-ghCli fallback cases.
- Add useSetupReadiness hook to evaluate setup state and expose actionable warning metadata
- Add reusable SetupWarningBanner component with compact and full warning presentation modes
- Render setup warnings in NewTaskModal and QuickEntryBox so task creation surfaces missing configuration early
- Add targeted tests for the hook and banner plus integration coverage updates for modal and quick-entry behavior
