Standalone JSON reviver for Chat SDK objects. Restores serialized Thread, Channel, and Message instances during JSON.parse() without requiring a Chat instance. This is useful in environments like Vercel Workflow functions where importing the full Chat instance (with its adapter dependencies) is not possible. Thread instances created this way use lazy adapter resolution — the adapter is looked up from the Chat singleton when first accessed, so chat.registerSingleton() must be called before using thread methods like post() (typically inside a “use step” function).
