Doesn't really seem like calorie restriction. The monkeys who died younger would have definitely been considered unhealthy and gluttonous. And it's no secret that being overweight causes premature aging, health problems and eventually premature death.

They controlled for diet, natural feeding tendencies, etc. presumably to match conditions in the wild. They never said the monkeys who "naturally" ate the most DIDN'T die first; they probably did. But that certainly doesn't mean that calorie restriction below the "average" feeding tendency doesn't provide benefit.

Does that imply that lifting, building up one's body and consuming excess calories to bulk up is somehow stressful for the body's metabolic aging process?

In a sense, yes - to build up your muscles they must first be broken down, a cycle which is going to create some amount of stressful churn. If you think about any machine, a higher operating energy/intensity generally correlates to faster breakdown.

At the same time, humans in good shape are definitely healthier, and too much calorie restriction can lead to malnourishment.

There's a sweet spot somewhere, proponents of calorie restriction are basically saying to err on the side of eating less.
