Introducing new developer tools in the Vercel Toolbar

Introduces new developer tools within the Vercel Toolbar: an accessibility audit tool that checks against WCAG 2.1 Level A and AA rules, an Open Graph preview tool for social media card rendering, and an interaction timing tool to measure and optimize Interaction to Next Paint (INP). Also introduces the ability to use the toolbar in production via a Chrome extension, allowing evaluation of these tools on live sites.
