Importing the Chat instance into Vercel Workflow files pulls in adapter packages that depend on Node.js modules, which aren't available in the workflow sandbox. This adds a standalone `reviver` function exported from `chat` that deserializes Thread/Channel/Message objects without needing a Chat instance or its adapter dependencies. Also updates the durable chat sessions guide to use the standalone reviver and dynamic bot imports inside step functions. Closes #243 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
