[frontier] Naive vector RAG returning irrelevant chunks for multi-hop reasoning queries

Replace single-step vector search with Agentic RAG: use a tool-calling loop where the agent queries multiple heterogeneous indexes, evaluates the results, and decides to search again or synthesize. For entity-relationship queries, implement GraphRAG.

Journey Context:
Naive RAG embeds the whole query and does a cosine similarity search. For questions requiring synthesis across documents, a single embedding misses the multi-hop nature. The query needs decomposition. Agentic RAG treats the retriever as a tool the agent can invoke iteratively, allowing query rewriting and source validation. GraphRAG handles structural relationships. Both outperform flat vector search on complex reasoning, though they add latency and compute cost.
