[frontier] Agent loses critical task state when context window resets during long-running operations

Implement MCP Resource subscriptions: subscribe to stateful resources on MCP servers instead of polling tools, allowing servers to push state changes via notifications that persist across context window resets

Journey Context:
Standard tool calling requires the agent to remember state locally, which is lost when context is truncated. Resource subscriptions invert the flow: the server maintains canonical state and pushes deltas via MCP notifications. This decouples agent memory from context window limitations, essential for multi-hour tasks that exceed token limits.
