Disable Parallel Tool Calling in react agent

[akshatjain546]

Is there any option in the prebuilt react agent to disable parallel tool calling like is is mentioned here: https://python.langchain.com/v0.2/docs/how_to/tool_calling_parallel/?

It would be nice to disable altogether, but perhaps a better solution would be to allow tools to be declared as sequential or parallel-able in nature.

Something like:

@sequential
@tool
def my_tool():
    ...

When the model calls this tool, it cannot call other tools at the same time.

We don't have that ability yet, but will look into it

Hey @vbarda,

I've raised a PR that adds a boolean in the prebuilt react-agent to disable parallel tool calls. If possible, can you take a look at this: #1720

Thanks!
