[frontier] Multi-agent orchestration creating bottlenecks with central orchestrator

Replace orchestrator-worker topology with the Handoff pattern: agents directly transfer control to other agents by returning a handoff tool call, eliminating the central orchestrator as a single point of failure and context bottleneck.

Journey Context:
The orchestrator-worker pattern forces all context through one agent, creating a chokepoint. The Handoff pattern, introduced by OpenAI's Swarm, lets any agent transfer full conversation context to another agent. Handoffs are implemented as tool calls—an agent calls a \`transfer\_to\_agent\_X\` function, and the receiving agent gets the full conversation history plus a \`context\` payload. This creates a flat peer-to-peer topology instead of a hierarchical one. Tradeoff: without a central chokepoint, guardrails are harder to enforce. Mitigate by injecting guardrail checks at each handoff boundary. This pattern wins for open-ended tasks where the path isn't known in advance; stick with orchestrator-worker for deterministic, auditable workflows. Critical implementation detail: always include a \`reason\` field in the handoff so the receiving agent knows why it was invoked.
