    fix(llm): failed to remove vectors when updating vid embedding (#243)
    
    ## Bug Report
    After deleting vertices, running `update_vid_embedding` does **not**
    successfully remove the corresponding vectors.
    
    ### Initial State
    
    * 13 vertices
    * 13 `vid` embeddings
    
    ### After Clearing Graph Data
    
    * 0 vertices
    
    ### After `update_vid_embedding`
    
    * Output shows: “Removed 13 vectors”

    However, calling `get_vector_index_info` still shows 13 `vid`
    embeddings.
