Subject: [PATCH] fix(windows): hide console window when spawning browser
 processes

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.
