[frontier] Build complex multi-agent orchestration with handoffs, shared state, and inter-agent communication protocols

Wrap specialized agents as tools with clear input/output schemas and let a single orchestrator agent call them like regular function calls. Eliminate handoff protocols and shared mutable state — each agent-as-tool receives its input, returns its output, and has no persistent state between calls.

Journey Context:
The multi-agent space is obsessed with handoff protocols, shared memory stores, and agent-to-agent messaging. But the simplest and most robust pattern winning in production is agent-as-tool: each sub-agent is a tool with a structured input \(task description plus relevant context\) and a structured output \(result\). The orchestrator doesn't need to know it's calling an agent versus a regular API. This eliminates the complexity of handoffs, shared state management, and context transfer. OpenAI Swarm popularized handoffs, but in practice the tool-calling pattern composes naturally with existing tool-use infrastructure and MCP. Tradeoff: sub-agents can't maintain conversation state across calls — each invocation is stateless. But this is a feature, not a bug: it forces clean interfaces, prevents context leakage between agents, and makes each sub-agent independently testable.
