[synthesis] Model stuck in infinite retry loop with identical invalid tool arguments after execution error

Implement a retry counter in the tool response metadata. If a tool fails twice with the same args, append 'STOP RETRYING' to the error message and switch the model's temperature to 0.7 to force exploration.

Journey Context:
When a tool returns an error \(e.g., 400 Bad Request\), models attempt to fix the arguments. Claude is generally good at self-correction. GPT-4o, however, often gets stuck in a local minimum, retrying the exact same invalid arguments 3-5 times before giving up. Gemini might hallucinate a success. Simply returning the error string isn't enough. You must break the model out of its deterministic loop by altering the temperature or adding aggressive anti-retry instructions in the error payload.
