Report #16389

[architecture] Orchestrator bottleneck in star topologies

Allow peer-to-peer handoffs for specialized execution, keeping the orchestrator only for initial routing and final synthesis. Use the orchestrator to hand off control, not just delegate and wait.

Journey Context:
In a strict star topology, the orchestrator must maintain the entire context, process every intermediate step, and relay messages. This centralizes state but makes the orchestrator a massive, slow, expensive LLM call. By allowing agents to hand off control directly \(e.g., Agent A transfers the conversation to Agent B, who then transfers to Agent C\), the orchestrator is bypassed during execution, reducing latency and cost.
