Seeded jitter values API

Generates a reproducible series of jittered delay values around a base (full-jitter on a configurable spread fraction). The value-add: deterministic backoff jitter for tests that need stable timings. Answers 'Give me deterministic jitter for retries', 'How do I reproducibly jitter a delay?'.
