[cost\_intel] Using a single expensive model for all requests regardless of difficulty

Implement a model cascade: route requests to a cheap model first, and only fall back to an expensive model if the cheap model fails validation or expresses low confidence.

Journey Context:
In any workload, 80% of queries are easy and 20% are hard. If you use a frontier model for everything, you overpay for the easy 80%. By using a cheap model \(or a classifier\) to triage requests, you only pay the premium for the frontier model when necessary. You can use a simple heuristic \(e.g., query length, presence of specific keywords\) or a small classifier to route. This drastically reduces average cost per query while maintaining high quality.
