Query About Refactoring Plan of Knowledge Base & RAG and Its Support for HarnessAgent

Currently, the knowledge base and RAG docking capabilities of AgentScope are only implemented in ReAct mode and marked as to be refactored. Besides, there is no configuration entry or enablement entry for such features in HarnessAgent. As knowledge base capability is essential for enterprise-level agent scenarios, we would like to inquire about the refactoring roadmap of this feature, and whether HarnessAgent will support knowledge base and RAG docking in the future.
