## Title

    [opentelemetry-python-genai] [genai-langchain] LangGraph interrupt/resume logs AttributeError warnings

## Body

    ## Observed symptom
    [genai-langchain] LangGraph interrupt/resume logs AttributeError warnings
    
    > [!NOTE] > This issue was created with AI assistance and needs to be verified.
    
    LangGraph dispatches `on_interrupt` and `on_resume` to every registered callback handler. `OpenTelemetryLangChainCallbackHandler` defines neither, so `langchain_core` logs an `AttributeError` warning each time a graph pauses or resumes (e.g. human-in-the-loop flows).
    
    ## Environment
    GitHub open-telemetry/opentelemetry-python-genai #828
    
    ## Trigger / context
    Public GitHub report in open-telemetry/opentelemetry-python-genai (FRESH_7D).
