 * Test suite for Auto Run setup wizard E2E tests
 *
 * Prerequisites:
 * - App must be built: npm run build:main && npm run build:renderer
 * - Tests run against the actual Electron application
 *
 * Note: Some tests may require dialog mocking for native file pickers.
 * The wizard flow is:
 * 1. Agent Selection - Choose AI agent (Claude Code) and project name
 * 2. Directory Selection - Select project folder
 * 3. Conversation - AI project discovery
 * 4. Phase Review - Review generated plan and create documents
