Initial setup of Vercel Workflow DevKit before workflow is installed. Fetch the official getting-started guide for the user's framework.
0) Sanity check Read package.json. If workflow is already a dependency, tell the user to use /workflow instead (it reads versioned docs from nodemodules/workflow/docs/). Only continue if workflow is missing.
1) Determine the framework Non-interactive: If the user named a framework in their prompt, use it directly.
Install and configure Vercel Workflow DevKit before it exists in node_modules. Use when the user asks to "install workflow", "set up workflow", "add durable workflows", "configure workflow devkit", or "init workflow" for Next.js, Express, Hono, Fastify, NestJS, Nitro, Nuxt, Astro, SvelteKit, or Vite.
