[cost\_intel] Using GPT-4o for security vulnerability detection in code review

Use o1 for detecting SQL injection and auth bypass in PR diffs; use GPT-4o for style/naming only. Chain them: GPT-4o filters for obvious issues, o1 deep-dives on hot paths.

Journey Context:
Instruct models catch linting/syntax issues but miss second-order data flow vulnerabilities. Reasoning models trace taint analysis mentally. The cost-per-critical-bug-found is 10x lower with o1 because catching one SQL injection justifies the API cost, whereas style fixes are commoditized.
