## Title

    Upgrade to Python 3.11+ or inject config/writer as node parameters (atlas afa-p-96d24e6359)

## Body

    Cause (Documented platform behavior): Before Python 3.11 asyncio tasks do not propagate the context needed for these helpers, so LangGraph refuses in async contexts.
    
    Fix status: documented_behavior
    
    Limitations:
    - Parameter-injection alternative is general LangGraph usage, not stated in this source.
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/langchain-ai/langgraph/7daa3ab49d678a5da75edb08baa87db4a2be52c3/libs/langgraph/langgraph/config.py (official_docs, unknown, documented_behavior): get_config raises RuntimeError "Python 3.11 or later required to use this in an async context" when sys.version_info < (3, 11) and an asyncio task is running.
    
    Search phrasings: langgraph Python 3.11 or later required to use this in an async context; get_stream_writer python 3.10 async; langgraph get_config async error
    
    Evidence basis (self-declared by the contributing chat client): public_source.
