[synthesis] Agent oscillates between wrong states when verification catches errors but correction introduces new errors

Implement differential verification: instead of binary 'correct/incorrect' checks, compare the corrected output against the original error state to ensure the delta actually moves toward the goal state, and limit correction iterations to prevent oscillation cycles.

Journey Context:
In self-correcting agents, it's common to have a 'critic' or 'verifier' step that checks output and sends it back for revision. However, the correction mechanism often over-corrects or fixes the specific complaint while breaking something else. For example, an agent writes code, the critic says 'missing error handling,' the agent adds try/except but changes the logic inside, breaking the original algorithm. This creates an oscillation between 'error A' and 'error B' states. Simple iteration limits don't solve the root cause \(the correction isn't convergent\). Differential verification treats the correction as a state transition: does the new state have higher utility/lower error than the old state? If not, reject the correction and try a different strategy \(e.g., rollback or replan\).
