On Windows, spawning chrome-headless-shell.exe and taskkill commands creates visible console windows. This adds windowsHide: true to child_process.spawn() and spawnSync() options to hide these windows. Fixes console window appearing during headless browser operation on Windows.

Tested on Windows 11 with Playwright 1.57.0 running chromium in headless mode.
