The Deployment analyzer dereferenced *deployment.Spec.Replicas without a
nil check. Spec.Replicas is a *int32 and, although the API server usually
defaults it to 1, a Deployment object whose replicas field is explicitly
unset (nil) panics the analyze run with a nil pointer dereference.
Guard the comparison with a nil check, mirroring the sibling StatefulSet
analyzer which already checks Spec.Replicas != nil before dereferencing.
Add a regression test that analyzes a Deployment with nil Spec.Replicas
and asserts Analyze does not panic.
