Two drifts corrected:
- registerAgent helper missing required environmentId (spec: 400 if absent).
- sendGroupCommand is now synchronous request-reply: returns 200 with an
aggregated CommandGroupResponse {success,total,responded,responses,timedOut}
— no longer 202 with {targetCount,commandIds}. Updated assertions and name.
