Live sent duration 0.0 in all 744 successful EnableRebuild (cancels
carry the time spent building, which DLU already matches); DLU sent
the reset time.
Tests get EntityManager::_addEntity/_removeEntity to make an entity
built outside CreateEntity findable, and helpers that read game
messages back out of captured packets.
Check: finish a quickbuild; the build completes, the celebrate
animation plays and the built object stays up for its usual time
before resetting.
