Re-introducing the Cloudflare Workers Playground

Cloudflare has revamped its Workers playground, focusing on the Worker-as-origin use case where the Worker is responsible for returning the full response. The updated playground includes an authenticated dashboard editor experience powered by VSCode, offering multi-module support, type-checking via JSDoc comments and the `workers-types` package, pretty error pages, and real previews that update as you edit code. It provides access to Chrome DevTools technology for visibility into the Worker, an "HTTP" tab for testing against various HTTP methods, and a new way to share your playground code through unique URLs which can be deployed instantly to Cloudflare's global network using a "Deploy" button.
