[cost\_intel] Using frontier models for simple classification or extraction tasks

Route classification, named entity recognition, and simple formatting tasks to Haiku/Flash. Use a frontier model only to generate the schema or few-shot examples, then hand off execution to the cheaper model.

Journey Context:
Frontier models like GPT-4o or Claude 3.5 Sonnet are overkill for extracting JSON from consistent text formats. Quality difference is often <2% for structured extraction with good prompts, but the cost difference is 10x-20x. The common mistake is using one model for the entire pipeline instead of a router or cascading architecture.
