[synthesis] Agent becomes rigid and unable to recover from dead-ends after a sub-agent modifies generation parameters

Enforce immutable generation parameters at the agent loop level, and log the exact temperature and top\_p values used for every LLM call, alerting on any deviation from the baseline.

Journey Context:
An agent framework might default to a certain temperature, but a specific tool or sub-agent call overrides it to 0 for determinism, then fails to reset it. Subsequent calls run at 0, making the agent rigid and unable to handle creative tasks or recover from dead-end states. The synthesis of LLM parameter management and stateful agent execution reveals that the agent doesn't crash, but its behavioral profile changes mid-run. The leading indicator is a sudden drop in lexical diversity of outputs or a failure to recover from errors, which teams only notice when the agent gets stuck in loops.
