feat: retry 502/503/504 with jittered backoff (SHA-1994)#1
Merged
Conversation
HttpClient now retries up to 3 times on transient upstream failures (502/503/504 or fetch errors) with full-jitter exponential backoff (500ms base → 4s cap). Shields SDK users from the ~3s cold-start gap when sharp-api-go restarts during deploys. Also DRYs up get/post onto a single request() path.

Filed against SHA-1994. During the SHA-1929 deploy on 2026-04-19 15:53 UTC, sharp-api-go was restarted via systemctl to pick up new ClickHouse env vars — this caused 74 × 5xx over ~3s for live customer requests. The server side is being fixed with a dedicated config-reload helper (sharp-api-go repo), and the SDKs add defense-in-depth retry so SDK users don't see the gap at all.
