[frontier] MCP agents losing state between turns due to tool-only integration patterns

Expose mutable state as MCP Resources with subscription patterns; agents read Resource state before writing via Tools, treating Resources as working memory segments.

Journey Context:
Developers initially treat MCP as just a tool-calling interface, leading to stateless request-response loops. The insight is that MCP Resources are first-class entities representing stateful documents or memory banks. By subscribing to Resource updates and explicitly reading/writing state through this abstraction, agents maintain coherence across long trajectories without stuffing everything into the context window.
