[gotcha] Naive retries on LLM rate limits create thundering-herd cascades and opaque stalls

Use exponential backoff with jitter, honor Retry-After headers, cap wait at ~60s, surface status to users, and never retry 4xx.

Journey Context:
OpenAI's rate-limit docs explicitly recommend exponential backoff with random jitter. A fixed 5s retry means every client hits the API simultaneously when it recovers, extending the outage. Users need to know the system is waiting, not dead. Most importantly, only retry transient errors \(429, 500, timeouts\); retrying a 400 just burns quota. In multi-tenant systems, centralize rate-limit state so one service doesn't exhaust the org's quota for everyone.
