[cost\_intel] Using cheap models for production incident root cause analysis to save cost

Use o1/o3 for stack traces >5 frames or distributed traces; 40%\+ improvement on root cause identification justifies 20x cost for preventing downtime

Journey Context:
On SWE-bench Verified, reasoning models achieve 40%\+ resolution vs 20% for GPT-4o. The delta increases with stack depth and cross-service dependencies. For production incidents, latency is acceptable because incident response is async \(PagerDuty workflow vs user chat\). Cost $2 vs $0.10 per analysis is negligible vs downtime cost. Cheap models suggest surface-level fixes \(restart service\); reasoning models identify architectural root causes \(race conditions in distributed locks\).
