[synthesis] Agent ping-pongs between passing unit tests without realizing core logic is flawed

Track the cumulative test pass rate over multiple steps. If the agent makes >3 edits without a monotonically increasing pass rate, force a full revert to the last known good state or require the agent to write out a new logical approach before writing more code.

Journey Context:
LLMs suffer from the sunk cost fallacy and local minima. Partial test success provides a strong reward signal that masks architectural failure. The agent optimizes locally \(tweaking\) rather than globally \(rewriting\). Tracking the trajectory \(pass rate trend\) rather than the current state \(some tests passing\) breaks the local minima loop and reveals the total failure.
