GitHub API rate limits

Resilience

Every registry call has a per-request timeout (REGISTRY_TIMEOUT_MS, default 15s), response caching (REGISTRY_CACHE_TTL_MS, default 5 min), retries with exponential backoff, and a per-registry circuit breaker. Client errors (including 404) do not trip the breaker. See Configuration.
