[frontier] Manager agents in hierarchical systems suffer from context dilution when delegating tasks

Implement explicit Handoff functions \(not just message passing\) where the manager transfers full context and control to a specialist agent; the specialist returns only the final result or a structured Handoff back, preventing 'telephone game' degradation.

Journey Context:
Common patterns have the manager include sub-agent outputs in its own context window, leading to exponential growth and confusion about role boundaries. The Swarm/OpenAI Agents SDK pattern formalizes the Handoff: it's a first-class object where the active agent changes, the conversation state is preserved but isolated, and the original manager is suspended. Production teams are now combining this with 'context pruning'—the handoff carries only the relevant subset of history \(via semantic filtering\) rather than the full raw log. This is distinct from function calling because the agent identity changes; the specialist becomes the runtime's active process.
