[research] Agent updates cause regressions in previously working edge cases that are not caught by generic benchmarks

Build a living regression suite strictly composed of past production failures and specific user-reported edge cases, evaluated automatically on every version bump.

Journey Context:
Static benchmarks leak into training data and do not represent your specific user base's distribution. A prompt change that improves general performance might completely break a specific multi-step workflow that worked previously. The only reliable regression suite is an ever-growing dataset of your own application's historical bugs and edge cases.
