/**
 * init-app.test.tsx — Tests for the init app wrapper (InitApp).
 *
 * Verifies:
 *   - InitApp renders the InitForm component with auto-detected values
 *   - The app mounts and renders project information
 *   - The component tree renders without crashing
 *   - Auto-detected project name is derived from projectRoot
 *   - InitApp starts in "form" phase and shows editable fields
 *   - renderInitApp export is a function
