Performance improvements and setting update for the Vercel Toolbar

The Vercel Toolbar has been updated to load up to 10 times faster and is now smoother due to hardware acceleration, providing features such as comments, feature flags, and development tools like the interaction timing tool. Users are given the ability to adjust toolbar visibility based on environment settings for their team or project from the dashboard. It can also be hidden or unhidden via keyboard shortcuts or through an option in the toolbar menu.
