🪲 Bug Report - -validateScenarioOnly should always output to host

## Describe the bug

When running a -validateScenarioOnly run without -FollowLog, it is not clear whether validation is successful because success has no output.

## To Reproduce

Steps to reproduce the behavior:

1. -validateScenarioOnly run without -FollowLog
2. Have a valid scenario

## Expected behavior

Return to the host whether or not the scenario is valid.

Start by reproducing a -validateScenarioOnly run without -FollowLog using a valid scenario, then trace the validation command's output path. Compare its behavior with -FollowLog enabled and verify that both valid and invalid scenarios report their result to the host.
