Run the Playwright end-to-end test suite for Tandem.
E2E tests will kill any running dev server. Playwright's webServer config starts its own servers on :3478/:3479, and freePort() kills existing processes on those ports. Do NOT run E2E tests while dev:server or dev:standalone is running unless you're OK losing that session.
Check for running dev servers and warn:
if curl -sf http://127.0.0.1:3479/health 2>/dev/null; then
echo "WARNING: Dev server detected on :3479. E2E tests will kill it."
echo "Stop your dev server first, or accept it will be terminated."
fi
Ask the user for confirmation if a server was detected.
Run the tests:
npm run test:e2e
For interactive debugging mode:
npm run test:e2e:ui
