Enum TimerOutcome 

pub enum TimerOutcome {
    Applied {
        status: SagaStatus,
    },
    SkippedPaused,
    SkippedFencingLost,
    SkippedStale,
}

业务作用：区分单个 timer 的处理结论，驱动领取循环决定交还还是继续。

Variants

Applied

timer 已消费并完成对应裁决。

Fields

status: SagaStatus

事务提交后的实例业务状态。

SkippedPaused

实例处于 PAUSED：不消费，由调用方按轮询退避交还。

SkippedFencingLost

fencing 失败：租约已被其它副本接管，旧 owner 立即停止。

SkippedStale

timer 语义已过时（状态/步骤已迁移），已按已消费吸收，无业务动作。
