Enhance retrieval pipelines: 4-stage GraphRAG, DocRAG grounding, consistent PROV-O GraphRAG: - Split retrieval into 4 prompt stages: extract-concepts, kg-edge-scoring, kg-edge-reasoning, kg-synthesis (was single-stage) - Add concept extraction (grounding) for per-concept embedding - Filter main query to default graph, ignoring provenance/explainability edges - Add source document edges to knowledge graph DocumentRAG: - Add grounding step with concept extraction, matching GraphRAG's pattern: Question → Grounding → Exploration → Synthesis - Per-concept embedding and chunk retrieval with deduplication Cross-pipeline: - Make PROV-O derivation links consistent: wasGeneratedBy for first entity from Activity, wasDerivedFrom for entity-to-entity chains - Update CLIs (tg-invoke-agent, tg-invoke-graph-rag, tg-invoke-document-rag) for new explainability structure - Fix all affected unit and integration tests
