[research] Running large-scale agent benchmarks before validating prompt changes causes wasted compute and cost

Implement eval-before-scale: run a small, highly deterministic smoke test regression suite \(5-10 cases\) on every prompt change before expanding to broader, more expensive evals.

Journey Context:
Developers often change a system prompt and immediately run a 1000-task benchmark. Because agents are stochastic and expensive, this wastes time and money if the prompt breaks basic functionality. A tiny, fast regression suite acts as a gatekeeper, catching catastrophic regressions in seconds before scaling up evaluation.
