[research] Scaling to multi-agent architectures before fixing single-agent failure modes

Run isolated evals on the core agent loop first. Do not introduce orchestrator agents or delegation until the worker agent achieves >90% on the target task suite in isolation.

Journey Context:
It is tempting to add 'manager' agents to route around failures, but this multiplies latency and cost while obscuring the root cause. A single agent failing 30% of the time will cause a multi-agent system to fail exponentially due to retry loops and context bloat. Fix the worker, then scale the architecture.
