[cost\_intel] Chaining multiple reasoning calls sequentially causing cost explosion

Use fast model for generation/draft, reasoning model \(o3-mini\) only for verification/critique steps

Journey Context:
Common anti-pattern is using o1/o3 for every step in an agent chain \(plan -> code -> debug -> test\), resulting in $5-20 per trace. Research shows 'verifier patterns' are more cost-effective: use GPT-4o for generation and coding, then o3-mini specifically for reflection steps or when confidence scores are low. This cuts cost 80-90% while preserving accuracy on complex tasks.
