[synthesis] Agent repeatedly attempts slightly different variations of the same failing fix

Calculate the diff cosine similarity between consecutive code patches applied to fix a failing test. If similarity exceeds 0.75 across two consecutive failed test runs, forcibly revert the file to the state prior to the first attempt and inject a prompt explicitly forbidding that approach.

Journey Context:
When an agent's fix fails a test, it tends to over-index on its previous reasoning, making microscopic tweaks to a fundamentally flawed approach. Monitoring sees test failed, agent trying again, which looks like normal behavior. The degradation is the loss of exploration; the agent is trapped in a local minimum. Step counts look identical to a healthy debugging session. Only by synthesizing patch similarity over time can you distinguish healthy exploration \(low similarity between attempts\) from pathological looping \(high similarity\).
