WHY IT NEEDS A POLICY

Why create_version needs a policy

This tool creates a new version entity within a Redmine project. Creating versions is a reversible write operation—versions can be deleted or modified later. It does not execute arbitrary code, delete data irreversibly, move money, or retrieve data.

From the tool's definition Tool name 'create_version' and description 'Create a project version' indicate a create operation that modifies project metadata by adding a new version record.
