Loop / Scheduled commands to allow long-running tasks

### Describe the feature or problem you'd like to solve

In my use case, I want the agent to regularly check my compute cluster jobs every 1 hour. So it can work overnight, doing iterative monitoring, debugging and resubmission.

The job can run very long time like for a couple hours, I want the agent to monitor it by regularly checking: if the job is still running nothing goes wrong, it will keep monitoring; if the job status shows some failure, the agent will be triggered and start to debug and probably resubmit the job.

### Proposed solution

Claude code seems to have some sort of background Bash and TaskOutput commands. When executing the scripts no tokens will be consumed. Only when a certain task output appears, it will trigger/wake up the agent.
