[counterintuitive] Using 'Let's think step by step' to force reasoning in modern models

Remove conversational CoT triggers; use explicit structural task decomposition or rely on native reasoning models \(o1/o3\) that handle CoT internally.

Journey Context:
Zero-shot CoT was a breakthrough for GPT-3/early GPT-4, but modern instruction-tuned models either natively chain thought or get distracted by forced conversational filler. 'Think step by step' often leads to verbose, low-signal rambling rather than logical deduction. For standard models, specify the \*method\* of reasoning \(e.g., 'Break the problem into state variables, then iterate'\). For reasoning models, explicit CoT instructions actively degrade performance by interfering with their internal reinforcement learning search.
