test(e2e): add Playwright global setup/teardown to kill ports and force clean exit; run React consumers via build+serve; batch port cleanup (Linux/macOS)\n\n- federated-css: kill ports before/after tests (globalSetup/globalTeardown)\n- federated-css-react-ssr: kill SSR ports before/after tests\n- start-all: switch React consumers to static build+serve; Next apps build+start\n- port cleanup: single kill-port CLI + multi-port lsof/fuser fallback (Linux focus)\n\nNote: Windows cleanup path dropped per scope — Linux/CI only.
