Cypress Playwright Setup

This sets up proper E2E testing infrastructure with either Cypress or Playwright, including page object models, fixtures for authenticated states, and CI-ready configurations. You get cross-browser testing configs, reusable page objects that abstract selectors, and fixture patterns that let you skip authentication in protected route tests. The Playwright setup includes parallel execution and retry logic, while the Cypress version adds Testing Library commands. Honestly, the page object pattern here is worth adopting even if you already have tests, it makes refactoring way less painful when your UI changes. Good for greenfield projects or teams moving from scattered test files to something maintainable.
