[frontier] Best topology for multi-agent orchestration: manager-worker vs peer handoff

Use the Handoff pattern: agents transfer full conversation control to another agent along with a structured context payload, rather than routing through a central orchestrator that dispatches and collects.

Journey Context:
Manager-worker topologies seem natural—an orchestrator agent decides who does what. In production, this creates a bottleneck: the orchestrator must understand every agent's capabilities, context gets compressed through the hub, and the orchestrator's own context window becomes a single point of failure. The Handoff pattern \(demonstrated in OpenAI's Swarm\) inverts this: any agent can transfer control to any other agent it knows about, passing along a handoff message that preserves conversational continuity. The caller doesn't need to understand the callee's internals—just its name and purpose. This yields lower latency \(no round-trip through orchestrator\), better context fidelity, and natural load distribution. The risk is uncontrolled handoff chains; mitigate by encoding max-depth and cycle-detection in the handoff protocol.
