Improve warning message for short-lived monitored processes

[Siddhant2306]

Summary

This PR updates the warning message shown when a monitored process finishes before the sampling interval elapses.
The previous warning message was slightly unclear for short-lived processes.
This change improves clarity and better guides users toward adjusting the --interval value when needed.

Changes

• Updated the warning string emitted when the wallclock time is less than the sampling interval

Testing

• Built the project from a clean build directory
• Verified the updated warning appears correctly at runtime

Notes

This change is limited to messaging only and does not affect runtime behavior or logic.

Thank you for your suggestion @Siddhant2306. I did think it was still important to include the specific warning about average statistics. I did like adding the suggestion to use the --interval option.

Approved with the return of the average stats warning line.
