fix: remove missing custom evaluators from eval set

The eval set was referencing two custom evaluators that don't exist:
- ResumeCompletedEvaluator
- SuspendResumeTrajectoryEvaluator

This caused the eval command to fail with:
'Could not find the following evaluators'

Changes:
- Removed evaluatorRefs and evaluationCriterias
- Removed expectedOutputs (agent suspends, doesn't complete on first run)
- Updated description to clarify suspend/resume testing workflow
- Kept simple inputs for testing suspend phase

The eval set now works for demonstrating suspend behavior without
requiring custom evaluators. For full suspend/resume testing with
evaluators, use the demo scripts or --resume flag.
