[architecture] Cross-session memory leaking between different users or projects in a multi-tenant agent

Scope memory retrieval by a strict namespace or tenant ID at the query level, and isolate vector embeddings per user/project if strict multi-tenancy is required.

Journey Context:
Developers often use a single global vector index with metadata filtering for multi-tenancy. However, if the metadata filter fails or is bypassed, cross-contamination occurs. For high-security agents, separate collections or strict namespace isolation is required. Tradeoff: Separate collections increase infrastructure overhead and cost compared to a single filtered index.
