[counterintuitive] Adding 'Let's think step by step' to force code reasoning

Remove generic Chain-of-Thought triggers; use task-specific structural instructions or rely on native reasoning models, only triggering explicit CoT where intermediate state is needed for debugging.

Journey Context:
In 2023, 'Let's think step by step' was a magic spell for base models to unlock reasoning. Modern instruction-tuned models already apply CoT natively when required. Forcing it on simple coding tasks causes latency and 'overthinking', leading to convoluted code or sycophancy where the model invents complex problems for simple requests. Modern RLHF penalizes unnecessary verbosity. Use explicit reasoning steps only for complex algorithmic logic.
