[nitpick] The pattern of checking for both existence and non-empty value is repeated across multiple env vars. Consider creating a helper such as lookupNonEmptyEnv(key string) (string, bool) to encapsulate this logic and reduce duplication.

Values containing only whitespace will pass the != "" check and may cause parsing errors. Consider using strings.TrimSpace(proxy_urls) before testing for emptiness to treat whitespace-only inputs as empty.
