[synthesis] Agent loops silently on test failures after a partial revert, trying the same fix repeatedly without erroring out

Implement a stateful 'fix attempt' counter based on the exact error message. If the identical test failure occurs twice consecutively, halt the loop and trigger a 'step-back' reasoning step or request human intervention.

Journey Context:
Agents often try to fix code by reverting changes. If they revert file A but the test also depends on file B \(which they modified earlier\), the test fails with the same error. The agent sees the same error, applies the same logic, and loops indefinitely. Without an explicit state check on the error message rather than the tool output, the agent cannot detect it is stuck. Simply limiting max iterations is a blunt instrument; detecting a repeated error state is precise and allows the agent to try a completely different approach.
