Reads the most recent HEALTH_DIAG aux_moe line from the smoke log
and asserts: (1) no expert utilization < 2% (anti-collapse working),
(2) no expert > 80% (no snap-collapse to single expert), (3) gate
entropy < 0.9·ln(8) (peakier than uniform on average).
Failures are findings, not test infrastructure bugs — concrete numbers
reported per feedback_kill_runs_on_anomaly_quickly.md.
