WHY IT NEEDS A POLICY

Why create_annotation_queue needs a policy

This tool creates a new annotation queue, which is a write operation that modifies system state by adding a new resource. It is reversible (the queue can be deleted) and has no destructive or irreversible effects. The blast radius is limited to the annotation queue system itself, making it low severity.

From the tool's definition Tool name contains 'create' indicating data creation. Description states 'Create a new annotation queue' which is a reversible write operation.
