* Add support for ToolOutput response format.
* I don't love the name -- it's confusing unless you know that it's parameterizing a strategy.
We should determine if we want to support our old strategy for doing
things -- it has a higher latency (one extra LLM call), but it's a
reasonable built-in strategy as it doesn't do anything awkward with
conversation history. (Wouldn't surprising if it has overall better
performance than tool choice for longer conversations)
Add option to split tool node to individual nodes.
Summary:
* User code (specifically streaming) may break if it's relying on the
name of the `tools` node
* The boolean flag in the interface is likely **temporary** (especially
if there are no major breaking changes)
* We'll need to decide if we can get rid of the version in create react
agent. "v1" is not consistent conceptually with a node per tool.
