Current Behavior:
The intMax helper function is implemented independently in both:

pkg/reconciler/autoscaling/kpa/kpa.go
pkg/reconciler/autoscaling/hpa/hpa.go

Both implementations are functionally identical but maintained separately.

Problem:
Duplicate logic means any future change to intMax needs to be applied in two places, increasing maintenance overhead and the risk of the implementations diverging over time.

Proposed Solution:
Move intMax to a shared internal package (e.g. pkg/reconciler/autoscaling/resources) and update both reconcilers to use the shared implementation instead of their local copies.
