Add support for downloading and displaying Playwright E2E test reports
in the GitHub Pages deployment workflow. The reports are organized by
browser (chromium, chromium-2x, chromium-0.5x, mobile-chrome) and
presented via an interactive index page with test statistics.
Changes:
- Download Playwright reports from CI test runs (both triggered and latest)
- Organize reports into browser-specific directories
- Create interactive index page showing test stats (passed/failed/skipped/flaky)
- Integrate with existing .pages landing page
