[cost\_intel] Using o1 for linting and syntax fixes, paying $0.20 per review for what Sonnet does for $0.003

Use Claude 3.5 Sonnet/GPT-4o for style/syntax review; use o3/o1 only for architectural reviews spanning >5 files or detecting subtle concurrency bugs. The cost cliff is 50x with no quality gain on linting.

Journey Context:
On datasets like CodeReviewPredict, o1 shows 25% higher acceptance rate on 'design pattern violations' \(e.g., 'this violates the Single Responsibility Principle'\) compared to Sonnet. However, on 'missing semicolon' or 'unused import' style issues, both models achieve 99% precision but Sonnet is 60x faster and cheaper. The degradation signature for cheap models is missing cross-file dependencies; if the review requires 'find all callers of this function and check for null', reasoning models justify the cost.
