[frontier] Multi-agent systems fail when sub-agents cannot request clarification or additional context from parent agents

Use MCP 'sampling' capability to allow server agents to request LLM completions from client agents, enabling recursive delegation with controlled budget; implement in parent-child agent topologies

Journey Context:
Traditional multi-agent uses static handoffs; when a sub-agent hits ambiguity, it guesses or fails. MCP sampling lets a server \(tool\) ask the client \(host agent\) to 'think harder' or retrieve specific context, maintaining the chain of custody for tokens and permissions. This replaces brittle 'agent as tool' wrappers with protocol-native delegation.
