Nuno CamposandGitHub cf7f6691cf Improve typings for task, it now returns a mixed sync/async future protocol (#3186)

cannot make it a protocol as it inherits from concurrent.futures.Future)

 		39552255c8 langgraph: add support for BaseModel updates to Command (#2747) 
Simple update that adds support for the `update` attribute of the
`Command` class to support Pydantic `BaseModel` type.

LangGraph already supports [Pydantic models for graph
states](https://langchain-ai.github.io/langgraph/how-tos/state-model/).

Extending support to the `update` attribute allows users to pass custom
BaseModel instances. Additionally, updates defined as `BaseModel` types
are type-validated when created.

Eugene YurtsevandGitHub 5dc5853161 Add entrypoint.final to decouple return value from save value (#3135) 
* Introduce `entrypoint.final` that allows decoupling what's returned
from the state update.
* moving decorator to class object w/ call to support defining `final`
as a property on it -- this should play nicely w/ IDE tooling / type
checking.


```python
    previous_ = None

    @entrypoint(checkpointer=MemorySaver())
    def foo(msg: str, *, previous: Any) -> entrypoint.final[int, list[str]]:
        nonlocal previous_
        previous_ = previous
        previous = previous or []
        return entrypoint.final(value=len(previous), save=previous + [msg])

    assert foo.get_output_schema().model_json_schema() == {
        "title": "LangGraphOutput",
        "type": "integer",
    }

    config = {"configurable": {"thread_id": "1"}}
    assert foo.invoke("hello", config) == 0
    assert previous_ is None
    assert foo.invoke("goodbye", config) == 1
    assert previous_ == ["hello"]
    assert foo.invoke("definitely", config) == 2
    assert previous_ == ["hello", "goodbye"]

```

Bhavya DhimanandGitHub c48d495031 fix(requirements.txt): Set requirements path to posix expression so that it can work in windows OS as well. (#3101) 
When I cloned langgraph example, I was not able to run the code because
of the requirements.txt file. The path was set to posix expression which
was not working in windows OS.
I have updated the path to posix expression so that it can work in
windows OS as well.

Try running `langgraph-example` in windows using the langgraph-cli in
windows OS. It was working for linux not in windows.
