[counterintuitive] Always providing few-shot examples to guarantee better output formatting and accuracy

Default to zero-shot with explicit formatting instructions; only use few-shot if the desired output is highly idiosyncratic and impossible to describe schematically.

Journey Context:
Modern frontier models have strong prior distributions for standard formats \(JSON, Markdown\). Few-shot examples often anchor the model to the specific style or errors present in the examples, degrading performance on complex tasks. Zero-shot with clear instructions allows the model to use its native capabilities fully. Few-shot is still useful for non-standard formats but is no longer the default best practice for modern models.
