[cost\_intel] High-latency reasoning models blocking synchronous UI threads

Move reasoning to async background jobs with polling/webhooks, or use streaming fast-model fallback while reasoning processes

Journey Context:
Reasoning models \(o1/o3\) often take 10-30s\+ which kills UX for chat interfaces. Common mistake is waiting for full completion on the critical path. Better pattern is using fast models \(GPT-4o\) for immediate streaming response while heavy reasoning happens asynchronously, or using webhook callbacks for long-running analysis tasks.
