Cron announce 去重：避免 isolated 作业向同一渠道发送双消息
场景：isolated agentTurn + delivery.mode=announce 时，作业结果可能被发送两次（一次来自 isolated 结果，一次来自 main session 唤醒）。该修复通过 delivered 标记阻止重复派发。

Prerequisites
- OpenClaw version includes PR #15739 (or a later release containing it).
- You can create isolated cron jobs with delivery.mode=announce.
Steps
- Create a reproducible test job using isolated agentTurn + announce mode, and run it once before upgrade to capture baseline behavior.
- Upgrade to build containing PR #15739 and restart gateway cleanly.
- Run the same cron job 3-5 times (including `cron run` manual trigger and scheduled trigger).
- Compare run history with target channel output; each run should map to exactly one delivered message.
Commands
openclaw gateway statusopenclaw gateway restartopenclaw cron run <jobId>openclaw cron runs <jobId>openclaw logs --local-timeVerify
For each run id, exactly one outbound announce message appears; no extra main-session duplicate is generated.
Caveats
- If channel plugins retry on provider/network errors, apparent duplicates may still occur outside cron logic（需验证）.
- Do not mix this check with multi-recipient broadcast jobs; validate single target first.
