[frontier] RAG retrieval missing temporal context and relationships

Replace vector search with GraphRAG indexing that extracts entities and relationships, then wrap updates in Temporal workflows to maintain point-in-time consistency for agent memory.

Journey Context:
Naive RAG fails when agents need to reason about evolving relationships \(e.g., 'User previously preferred X but switched to Y'\). Simple chunking loses temporal and relational context. Microsoft GraphRAG extracts knowledge graphs from documents, preserving these relationships. However, without versioning, agents see inconsistent snapshots. By orchestrating GraphRAG index updates through Temporal.io workflows, you ensure agents query immutable point-in-time views of the knowledge graph, preventing the 'time travel' bugs where an agent sees future knowledge in a past context.
