[research] Scaling agent autonomy or parallel runs leads to compounding failures

Implement eval-before-scaling: lock agent architecture and prompt changes behind a regression suite, and gate parallel execution limits based on the error rate of the lowest-performing sub-agent.

Journey Context:
Developers often increase autonomy \(e.g., allowing 10 parallel runs or higher loop limits\) to improve success rates, but this linearly scales cost and multiplies the blast radius of a bad tool call. You must prove the single-threaded agent is highly reliable \(e.g., >90% tool success\) before granting it more compute or autonomy, otherwise you just scale waste.
