[cost\_intel] Uniform routing of all requests to reasoning models for 'quality safety'

Implement a two-tier router: GPT-4o attempts generation first; o3-mini validates output only when confidence <0.9 or task complexity score >7/10. This reduces reasoning costs by 60-80% while maintaining 99% accuracy.

Journey Context:
Full reasoning throughout a pipeline is wasteful for the 80% of inputs that are routine. However, cheap models hallucinate on the critical 20%. The optimal architecture is a 'critic' pattern: fast generation, slow verification. This beats pure routing because o3-mini as a verifier sees the candidate output, reducing the search space compared to generation from scratch. Cost analysis shows break-even at 40% verification rate; below this, the overhead of double inference dominates; above it, the accuracy gains justify the cost.
