Rate Limit Backoff Planner

Design smarter retry behavior for 429s, 503s, flaky networks, and transient API failures. Compare fixed, linear, and exponential schedules, add jitter, honor caps, and copy production-ready code snippets without doing the math by hand.

Full jitter usually behaves best under contention because it spreads retries across clients. If you are handling 429 Too Many Requests, prefer honoring Retry-After whenever the upstream sends it.

This policy spreads retries well and keeps the worst-case wait reasonable for typical API clients.
