[research] Scaling agent parallelism causes cascading failures and rate limits from untested prompt changes

Enforce an eval-before-scale gate. Run a deterministic regression eval suite against a static dataset on every prompt or logic change. Only increase concurrency or agent pool size if the regression eval passes and token variance is within bounds.

Journey Context:
It is tempting to throw more compute at an agent to improve throughput. However, if a prompt change introduces a 10% increase in retry loops, scaling it up will immediately hit rate limits and degrade the whole system. Eval-before-scaling prevents amplifying small logic bugs into systemic outages.
