[cost\_intel] Attempting complex multi-step planning with small models to save money

Use a planner-executor pattern: frontier models \(Opus/GPT-4\) for planning, small models \(Haiku/Mini\) for execution.

Journey Context:
Small models fail at multi-step reasoning because they lose track of constraints or hallucinate dependencies. Cost savings from using a small model are wiped out by the need for 3-4 retries or human correction. A planner-executor pattern yields 90% of the cost savings with 100% of the quality, as the expensive model only processes the high-level logic once.
