WHY IT NEEDS A POLICY

Why update_plugins_config needs a policy

This tool modifies configuration data (plugins.js) in a reversible manner. While updates are not strictly deletions, they alter the runtime behavior of the application and could break the project if misconfigured. This is Write rather than Execute because it configures rather than runs code directly, and it's reversible (configurations can be changed back).

From the tool's definition Tool name is 'update_plugins_config' and description states it updates 'plugins configuration in js/plugins.js', which is a core configuration file for RPG Maker MZ projects.
