[frontier] Naive RAG retrieves disconnected chunks failing on complex multi-hop reasoning queries across documents

Replace vector search with GraphRAG: extract entities/relationships to build a knowledge graph, then use global search with community summaries for holistic reasoning over scattered evidence

Journey Context:
Standard RAG hits context limits and misses implicit relationships \(e.g., 'How did X influence Y via Z?'\). GraphRAG indexes by semantic communities, not just vectors, preserving relational context. While indexing is costlier, it eliminates hallucinated connections and provides provenance trails via graph paths. Critical for research agents requiring synthesis across thousands of documents where simple embedding similarity fails.
