[Improvement] Add a job failure handling mechanism to the job system.

### What would you like to be improved?

There is currently no failure handling mechanism in job system.

### How should we improve?

_No response_

The issue does not name files, tests, or entry points. Start by locating the job system and documenting its current execution flow, then clarify the failure states, handling behavior, and tests needed before implementation can be considered complete.
