WHY IT NEEDS A POLICY

Why inject_powershell_unmanaged needs a policy

This tool executes code (PowerShell) directly via injection, which is an Execute category action.

From the tool's definition Tool name 'inject_powershell_unmanaged' and description 'Execute unmanaged PowerShell' explicitly indicate execution of arbitrary PowerShell code. 'Unmanaged' execution bypasses security constraints and allows direct code injection.
