[research] Scaling agent parallelism increases costs and failure rates instead of throughput

Run eval suites on single-agent/single-thread runs first. Only increase parallelism or agent complexity after passing a strict regression suite. Do not scale concurrency to overcome latency; fix the agent logic first.

Journey Context:
When agents are slow, the instinct is to throw more parallel workers at the problem. However, flaky agent logic compounds under concurrency \(rate limits, shared state race conditions\). Eval-before-scaling ensures the baseline logic is deterministic and correct. Scaling a broken agent just creates expensive, concurrent failures.
