[research] Multi-agent system performance degrades when adding more agents instead of improving

Run single-agent evals on sub-tasks first. Only scale to multi-agent handoffs if the sub-agents pass their individual evals with high reliability; otherwise, you just multiply error rates.

Journey Context:
There is a temptation to throw more agents at a complex problem. However, if a sub-agent has a 20% failure rate, handing off to it creates a cascading failure point. Multi-agent orchestration adds overhead, context loss, and handoff failures. Ensure the atomic agent capabilities are solid and eval'd before distributing the workload.
