WHY IT NEEDS A POLICY

Why playwright_go_forward needs a policy

This tool triggers a browser navigation action (moving forward in browser history), which is an external operation that causes the browser to load a new page. It falls under Execute as it performs a browser action whose effects depend on the current state of the browser session. It's not purely Read since it changes the browser state, and not Write/Destructive as it doesn't modify or delete data directly.
