To me, reading those doesn't tell me what is happening. If one runs with `--verbose`, the SDK logs give the hint:

Maybe more information could be shown on failure on the default verbosity level.

Reproduce the failure with `workshop launch --wait-on-error` and compare its default output with the same command using `--verbose`. Trace the launch error and task display entry points to find where the health message is omitted. Done means the default failure output includes enough actionable detail to identify the issue, while preserving the continue, abort, and task-inspection guidance.
