[counterintuitive] AI gets stuck in hallucination loops when debugging failing tests

Limit the AI to a maximum of 2 attempts at fixing a failing test. If it fails twice, force the agent to read the runtime error logs and stack trace verbatim, or revert the changes and ask a human.

Journey Context:
When an AI's code fails a test, it often misdiagnoses the root cause and applies a localized patch that fixes the symptom but breaks something else, leading to a loop. Humans are overconfident but eventually step back and re-read the error. AI is systematically overconfident in its initial diagnosis and will 'dig in', generating increasingly convoluted code to satisfy the test without addressing the architectural flaw.
