[cost\_intel] Ignoring streaming as a mechanism for early termination on off-track generations

Use streaming not for UX alone but for cost-saving early termination: monitor the output prefix as it streams, and abort generation when the model is clearly going off-track \(hallucinating, wrong format, off-topic\). Saves the remaining output tokens on aborted requests.

Journey Context:
Streaming has identical token costs to non-streaming for completed requests—a common misconception is that it saves tokens. The real cost optimization is early termination. For long-generation tasks \(reports, code, analysis\), if the model starts hallucinating or going off-topic, streaming lets you detect this in the first 50-100 tokens and abort, saving the remaining 500-2000 output tokens. Without streaming, you pay for the full generation before you can evaluate it. At scale, if 10% of generations go off-track and are aborted at 20% completion, this saves ~8% of total output token costs. Implement by checking streaming chunks against lightweight validators \(format checks, keyword presence/absence, length constraints\).
