Setup hangs on Windows 11 because Bun's child_process can't handle
Playwright's --remote-debugging-pipe (fd 3/4 pipe handles). Fall back
to Node.js on Windows for both the setup verification and server
runtime. macOS/Linux completely unaffected — all Windows code behind
IS_WINDOWS / process.platform === 'win32' guards.
Based on community PR #194 by @sozairali. Fixed sed -i portability
(perl -pi -e) in build-node-server.sh for macOS compatibility.
