+feature: add migrate command to set up OpenNext.js for Cloudflare
+
+This command helps users migrate existing Next.js applications to OpenNext.js for Cloudflare by automatically setting up all necessary configuration files, dependencies, and scripts. It provides an interactive package manager selection (npm, pnpm, yarn, bun, deno) with keyboard navigation and performs comprehensive setup including wrangler.jsonc, open-next.config.ts, .dev.vars, package.json scripts, Next.js config updates, and edge runtime detection.
