[architecture] Retry storm causing cascading failure in distributed system

Use full jitter \(random value between 0 and max delay\) combined with circuit breakers; avoid simple exponential backoff which synchronizes clients

Journey Context:
Developers often implement naive exponential backoff \(2^attempt\) which causes thundering herds when a failing service recovers, as all clients retry simultaneously. Full jitter randomizes the wait time across the entire interval \[0, 2^attempt\], desynchronizing clients. Additionally, without a circuit breaker to fail fast after consecutive errors, clients continue hammering the degraded service, preventing recovery.
