[synthesis] Configuration deployment resets LLM temperature or top\_p to defaults causing silent reasoning shifts

Log the exact generation config \(temperature, top\_p, presence\_penalty\) used for every request alongside the model version. Alert on any deviation from the baseline configuration.

Journey Context:
LLM behavior is highly sensitive to sampling parameters. A CI/CD pipeline might deploy a default config file that overrides the tuned production parameters. The agent doesn't crash; it just starts acting differently—maybe failing complex logic tasks because temperature is too high, or failing creative tasks because it's too low. Because the code and model are the same, teams look everywhere else. Logging the actual parameters used \(not just what is in the config repo\) is critical.
