IwoooS Monitoring / Alerting / Observability post-incident readback 只讀計畫產生器。

本工具讀取 monitoring owner response acceptance snapshot，建立事故後回讀
計畫：誰改了告警 / receiver / silence、何時異常、改前改後 alert state、
receiver 是否收到、stale / silence 是否造成 false green、如何 rollback 與防再發。
它不連 live Prometheus、不 reload Alertmanager、不套用 Grafana / SigNoz /
Sentry / Langfuse、不 reload OTEL、不改 receiver route、不建立 silence、
不送 Telegram、不 fire live alert、不跑 alert chain smoke、不 SSH、不 kubectl、
不讀 secret value、不保存 raw alert payload、不寫 production。
