Feature Request Description

DeepTutor currently integrates LightRAG capabilities directly within its core backend execution stack. While this tightly coupled approach is convenient for standalone deployments, it introduces resource overhead and creates data silos for environments that already run a dedicated, standalone LightRAG container shared across multiple independent local agent architectures.
