WHY IT NEEDS A POLICY

Why assign_to_load_balancer_rule needs a policy

Assigning VMs to load balancer rules modifies the active traffic routing configuration and network load distribution. This is reversible (VMs can be removed from rules), so it is Write rather than Destructive. However, the blast radius is high because incorrect assignments could disrupt network traffic, impact service availability, and affect multiple customer-facing systems.

From the tool's definition Assigns virtual machines to load balancer rule: the tool 'assign_to_load_balancer_rule' creates or modifies network load balancing configuration by associating VM instances with a load balancer rule. This is a write operation that changes infrastructure state.
