[frontier] Static RAG retrieval failing on multi-hop questions requiring sequential reasoning

Implement Agentic RAG where the retriever is an agent that can reformulate queries, decide to retrieve vs. use memory, and synthesize across steps using ReAct or OpenAI Tools loop

Journey Context:
Naive RAG fails when answers require connecting disparate documents. Purely vector similarity misses implicit relationships. Agentic RAG treats retrieval as an action space. The agent can 'search', 'read', and 'reason' iteratively. Tradeoff: higher latency and token cost, but significantly higher accuracy on complex queries. Alternative: multi-query retrieval \(insufficient for reasoning chains\).
