+`waitForCompletion`을 복사하거나 overlap flag를 만들지 마세요. fluo는 두 옵션을 모두 노출하지 않으며, 모든 cron task에 scheduler-level no-overlap protection과 in-process running guard를 함께 적용합니다. 같은 task instance가 아직 실행 중일 때 다음 tick이 도착하면 fluo는 새 실행을 queue하지 않고 해당 tick을 건너뜁니다. 따라서 NestJS에서 `waitForCompletion: true`였던 task는 마이그레이션할 때 이 옵션을 생략합니다. NestJS task가 `waitForCompletion`을 생략하거나 `false`로 설정해 의도적으로 overlapping run에 의존했다면 fluo에서 overlap을 활성화할 수 있다고 가정하지 말고 application-owned queue 또는 worker 뒤로 작업을 재설계하세요.

+NestJS `@Cron()` options are not a drop-in `CronTaskOptions` object. Rename NestJS `timeZone` to fluo `timezone`:

+// NestJS
+@Cron('0 9 * * *', { timeZone: 'Asia/Seoul', waitForCompletion: true })
+
+// fluo
+@Cron('0 9 * * *', { timezone: 'Asia/Seoul' })
+```

+Do not copy `waitForCompletion` or invent an overlap flag. fluo does not expose either option: every cron task uses scheduler-level no-overlap protection plus an in-process running guard. If another tick arrives while the same task instance is still running, fluo skips that tick instead of queueing another run. A NestJS task with `waitForCompletion: true` therefore omits the option when migrated. If the NestJS task left `waitForCompletion` unset or set it to `false` and intentionally depended on overlapping runs, redesign that work behind an application-owned queue or worker rather than expecting fluo to enable overlap.
