[cost\_intel] Chaining cheap generation with reasoning verification beats monolithic reasoning generation

Implement a Critic pattern: Fast model \(GPT-4o-mini\) generates draft → Reasoning model \(o3-mini\) acts as Critic/Editor \(pass/fail or specific edits\) → Fast model finalizes. This gives 90% of o3 quality at 25% cost.

Journey Context:
Research on LLM Critics \(CriticGPT\) shows that discriminating correctness is easier than generating correctness, especially for reasoning. Using o3 to generate a full codebase is slow and expensive; using o3 to 'review this function for race conditions' is fast \(shorter output\) and high-value. The 'Draft-Critic-Refine' loop leverages the fast model's fluency and the reasoning model's rigor without paying generation costs for reasoning tokens. This is distinct from 'Generate Cheap Verify Smart' \(which uses voting\); this uses active editing/critiquing.
