[research] Scaling agent parallelism before establishing a regression baseline

Run a deterministic regression eval suite on a subset of tasks; block deployment if pass rate drops below threshold, regardless of latency improvements.

Journey Context:
It is tempting to increase max\_concurrent\_agents or remove human-in-the-loop to speed up tasks. However, if a prompt change introduces a 5% tool-call error rate, scaling it 10x turns a minor annoyance into a massive API bill and broken state. Eval-before-scale is the agent equivalent of measure twice, cut once.
