[frontier] Agent loses context between tool calls when using Model Context Protocol

Implement MCP with persistent session IDs and server-side state storage, using the session capability to maintain context across multiple client invocations rather than treating each call as stateless.

Journey Context:
Most developers use MCP like a REST API—stateless requests. But the protocol supports stateful sessions via the session capability introduced in 2024-11-05 spec. This lets agents maintain long-lived connections with servers \(like databases or filesystems\) without rebuilding context each turn. The alternative—re-sending full context each request—hits token limits fast. Stateful sessions reduce latency and token usage by 60%\+ in multi-turn workflows.
