WHY IT NEEDS A POLICY

Why suppressByFiles needs a policy

Suppressing findings modifies the state of security scan results by marking certain findings as ignored or suppressed. This is a reversible write operation (suppressions can typically be removed, as evidenced by the sibling 'deleteSuppression' tool). The blast radius is medium because misuse could hide real vulnerabilities from security reports.
