WHY IT NEEDS A POLICY

Why tdarr_download_plugins needs a policy

Downloading and installing plugins modifies the system state by adding/updating plugin files on nodes. This is a Write operation as it creates or updates files reversibly. It is not Destructive since it doesn't delete data, and not Execute since it doesn't run code directly, though it could enable future execution of new plugins.
