Test Dual Grouping URI Implementation (Task #5)

This module tests the dual grouping URI functionality:
- Entity-level grouping (kGGraphURI) for complete entity graph retrieval
- Frame-level grouping (frameGraphURI) for targeted frame graph retrieval
- Proper frame structure analysis and grouping assignment
- Verification of include_frame_graph=True functionality
