[synthesis] Deterministic sampling at temperature 0 hides brittle reasoning that breaks on slight prompt changes

Run critical reasoning paths at low-but-nonzero temperature with multiple samples and check for consensus; do not treat single deterministic output as robust.

Journey Context:
Temperature 0 gives reproducible outputs, which feels safe, but reproducibility is not correctness. A reasoning chain that only works because of a specific token ordering will fail when the user paraphrases the prompt or when context shifts. Consistency across samples is a better signal than deterministic repetition. This is the swarm insight: one confident answer is weaker than several converging answers.
