Deploy to Cloudflare buttons are failing on demos using v0.3

[mattzcarey]

ai is now a peer dep of agents. Some of these demos are linked in docs which have a Deploy to Cloudflare button which now errors

wrangler 4.56.0

✘ [ERROR] Build failed with 1 error:
  ✘ [ERROR] Could not resolve "ai"
  
      node_modules/agents/dist/client-QZa2Rq0l.js:945:39:
        945 │       const { jsonSchema } = await import("ai");

    You can mark the path "ai" as external to exclude it from the bundle, which will remove this error and leave the unresolved path in the bundle. You can also add ".catch()" here to handle this failure at run-time instead of bundle-time.
