[architecture] Agent failing to answer questions requiring connecting multiple distinct pieces of information across memory

Replace single-step retrieval with iterative or multi-hop retrieval. Have the agent generate a search query, retrieve, read the results, and based on those results, generate the next search query until the chain is complete.

Journey Context:
A user asks 'Who was the lead architect of the project my manager worked on before joining us?'. A single vector search will fail because the query embedding doesn't match the document containing the project name. The agent needs to first retrieve the manager's previous employer, then search for projects at that employer, then find the architect. Single-step RAG only works for single-hop facts. Multi-hop requires an agentic loop over the retrieval tool.
