Implement dynamic graph memory update feature for simulations
- Added a new optional parameter `enable_graph_memory_update` to the simulation API, allowing real-time updates of agent activities to the Zep knowledge graph. - Introduced `ZepGraphMemoryUpdater` and `ZepGraphMemoryManager` classes to handle the background processing of activity updates, ensuring efficient API calls and data management. - Updated the README.md to include detailed instructions on the new graph memory update functionality and its configuration. - Enhanced the simulation runner to manage the lifecycle of the graph memory updater, including starting and stopping the updater based on user configuration. - Improved logging to track the status of graph memory updates, providing better insights into the simulation process.
