[architecture] Agents hallucinating shared long-term memory facts due to implicit background RAG returning outdated information

Implement explicit, versioned memory management via tool calls \(read/write\) rather than implicit background context injection, so agents consciously verify memory provenance.

Journey Context:
Background RAG feels magical but gives agents unverified, unversioned context. If Agent A writes a fact and Agent B reads it via vector search, Agent B might retrieve an older, contradictory embedding. By forcing agents to use explicit memory\_read and memory\_write tools with version IDs, they can verify they are acting on the latest truth. Tradeoff: Increases token usage per turn, but guarantees state consistency.
