[frontier] MCP server context not updating during long running agent task

Implement MCP Resource subscriptions and Sampling to allow agents to receive streaming environmental context and delegate user-approval loops, treating MCP as a bidirectional state synchronization layer rather than a stateless RPC.

Journey Context:
Early MCP implementations treated it as JSON-RPC function calling. In production, agents fail because they lack real-time environmental state changes and get stuck waiting for human-in-the-loop approvals. MCP Resources \(with subscribe/updated notifications\) let the server push state to the agent. MCP Sampling lets the server request LLM completions, enabling nested agentic loops where the tool itself can reason. This shifts MCP from a passive toolbelt to an active collaborator.
