fix(cli): show failure reason when benchmark job fails with no outcomes (#182)

When a benchmark job failed (e.g., scenario setup failure), the watch
and summary commands showed a generic 'No benchmark outcomes found'
message. Now displays the job failure_reason in red, and shows
'Benchmark job failed.' instead of 'completed!' for failed jobs.
