The helper previously set CI=true, which flipped Playwright's
`reuseExistingServer` to false. That caused Playwright to spawn its own
Vite dev server on :5173, colliding with the docker compose stack
(paratype-web-dev container).
Removing CI=true makes Playwright connect to the running dev server in
docker. Verified: 146/146 e2e tests pass against docker-compose.dev.yml.
