MAESTRO: add E2E test infrastructure and Auto Run setup wizard E2E test (Task 6.1)

- Install Playwright dependencies (@playwright/test, electron-playwright-helpers)
- Create playwright.config.ts for Electron E2E testing
- Add e2e/fixtures/electron-app.ts with Electron launch fixtures and helpers
- Create e2e/autorun-setup.spec.ts with 24 tests (13 active, 11 skipped pending dialog mocking):
  - Wizard Launch: keyboard shortcut, agent selection screen, Escape to close
  - Agent Selection Screen: Claude Code display, other agents, project name, keyboard navigation
  - Directory Selection Screen: (skipped - requires dialog mocking)
  - Document Creation Flow: (skipped - requires full wizard flow)
  - Wizard Navigation: step indicators, button states, Back navigation
  - Exit Confirmation: (skipped - requires dialog mocking)
  - Accessibility: keyboard-only navigation, focus management
- Add npm scripts: test:e2e, test:e2e:ui, test:e2e:headed
- Update .gitignore with e2e-results/, playwright-report/, test-results/
