Previously, if one cron job had a malformed schedule expression (e.g. invalid cron syntax),
the error would propagate up and break the entire scheduler loop. This meant one misconfigured
job could prevent ALL cron jobs from running.
Changes:
- Wrap per-job schedule computation in try/catch in recomputeNextRuns()
- Track consecutive schedule errors via new scheduleErrorCount field
- Log warnings for schedule errors with job ID and name
- Auto-disable jobs after 3 consecutive schedule errors (with error-level log)
- Clear error count when schedule computation succeeds
- Continue processing other jobs even when one fails
This ensures the scheduler is resilient to individual job misconfigurations while still
providing visibility into problems through logging.
