Adds a Cursor slash command that implements any feature end-to-end: deep research → TDD (Red/Green/Refactor) → integration test generation with device pause gate → external setup checklist → verified PR. Includes a FEATURE_REGISTRY covering 7 feature types (notifications, auth, payments, deep links, analytics, storage, camera/media) with per-type test scenarios, external setup steps, and files-to-touch. Stack-aware: adapts to architecture, state management, backend, platforms, and e2e tool from project-brief.yaml. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
