[frontier] Agent memory backend coupling prevents A/B testing vector databases in production

Implement MCP Resource Subscriptions to treat memory as a resource provider; agents subscribe to memory namespaces via MCP protocol \(uri scheme: memory://\{namespace\}\), allowing hot-swapping between Pinecone, Weaviate, or knowledge graph backends without agent code changes

Journey Context:
Teams currently hardcode LangChain VectorStore integrations or use framework-specific memory classes. This creates vendor lock-in and prevents gradual migration from costly hosted vectors to open-source alternatives. By elevating memory to an MCP Resource, agents consume memory through the same interface they use for tools, with the MCP server handling provider-specific logic. The tradeoff is slight latency overhead versus massive operational flexibility. Alternative considered: standardized client libraries \(fails because it still requires code changes and dependency upgrades\). This pattern matters because memory costs dominate agent infrastructure spend at scale, and teams need to benchmark providers without rewriting orchestration logic.
