migrate-tests-to-playwright

Migrates UI tests from Cypress, Selenium, Puppeteer, or Protractor to Playwright Test while preserving what each test verifies: translates idioms instead of lines, runs both suites where possible, and reports a migration status per test. Use when moving a suite or part of one to Playwright. To restructure tests that are already in Playwright, use the refactor-to-page-objects command.
