[frontier] Global RAG context bleeds across user sessions causing privacy leaks and context pollution

Provision per-session ephemeral vector stores with multi-tenancy isolation that are garbage collected after session termination instead of using global knowledge bases

Journey Context:
Naive RAG uses one shared knowledge base. In multi-tenant agent systems, this causes cross-contamination: user A's documents appear in user B's context. Per-session vector stores \(Weaviate multi-tenancy, Pinecone serverless with soft-delete\) isolate embeddings by session\_id. They can be populated with user-uploaded docs, then auto-deleted. Tradeoff: higher latency for first query \(index creation\), memory overhead, but eliminates privacy risk. Essential for B2B agents handling sensitive docs.
