[frontier] Flat vector retrieval misses multi-hop relational reasoning required for complex queries

Use GraphRAG: extract entities and relationships into a knowledge graph, index community summaries, and use global search for reasoning over connections

Journey Context:
Naive RAG treats documents as isolated chunks. Questions requiring synthesis across documents \(e.g., 'Compare the security models of A and B'\) fail because chunks lack relational edges. GraphRAG builds an entity graph and uses community detection to generate global summaries, enabling multi-hop reasoning across disparate sources.
