WHY IT NEEDS A POLICY

Why set_project_setting needs a policy

This tool modifies the project.godot configuration file, which controls core engine behavior, rendering settings, and project metadata. While reversible (can be undone), misconfiguration could break the project, disable features, or alter security-relevant settings. This is a Write operation with high severity due to the blast radius of incorrect project configuration.

From the tool's definition Tool name 'set_project_setting' and description 'Set or modify a setting in project.godot' explicitly indicate creation or modification of configuration data.
