LangGraph Checkpoint Base Interfaces

LangGraph-checkpoint provides the base interfaces for checkpoint savers within the LangGraph framework (version 4.0.1). It defines the fundamental persistence layer, allowing LangGraph agents to save and restore their state across interactions, which is crucial for features like human-in-the-loop workflows, conversational memory, and time-travel debugging. This library also includes a default in-memory checkpointer for testing and experimentation. It releases frequently, often in conjunction with the main `langgraph` library.
