fix: Windows support — Node.js server fallback for Playwright (#255) * fix: Windows support — Node.js server fallback for Playwright 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.

On macOS/Linux this evaluates identically ('/tmp', '/'); on Windows it uses os.tmpdir() and path.sep. Zero behavior change on Unix.
