fix(cron): delete deleteAfterRun jobs regardless of execution status

One-shot jobs with deleteAfterRun: true were only deleted when
status === "ok". When skipped or failed, they kept their past
nextRunAtMs and triggered an infinite 40ms loop.

Now deleteAfterRun: true jobs are deleted after execution regardless
of outcome (ok, skipped, or error), matching the intended semantics
of "delete after run".

Added tests for skipped and failed scenarios.
