Vercel Sandbox gains Claude Managed Agents; Chat SDK adds one-call agent action wiring

Vercel's May 25 update ships Claude Managed Agents into Vercel Sandbox and adds Grok Build 0.1 and Qwen 3.7 Max to AI Gateway. The Chat SDK's new built-in toolset wires read/write agent actions with a single function call — developers building pause-and-resume flows at form submissions or approval gates no longer need custom callback wiring.
