Enum RecoverableError 

pub enum RecoverableError {
    Retryable {
        node: String,
        attempt: usize,
        max_attempts: usize,
        reason: String,
    },
    FallbackTriggered {
        from: String,
        to: String,
        reason: String,
    },
}

可恢复错误 — 内部重试或 fallback 后继续。
