AI Summary

This patch release for @cloudflare/think adds two key improvements: the ability to end agentic loops early using new `TurnConfig.stopWhen` conditions while maintaining the existing `maxSteps` safety bound, and RPC-safe cancellation support for `chat()` turns with new callback and cancellation methods.

Key Highlights

Exposed additive `TurnConfig.stopWhen` conditions for early agentic loop termination
Added RPC-safe cancellation for `chat()` turns
New `StreamCallback.onStart()` callback for turn start handling
New `cancelChat()` method for cancelling in-progress chats
Retains `maxSteps` safety bound while allowing early termination via stop conditions

New Features

TurnConfig.stopWhen conditions allowing Think subclasses to end agent loops after designated tool calls
StreamCallback.onStart() callback for handling turn start events
cancelChat() method for RPC-safe cancellation of chat turns
