WHY IT NEEDS A POLICY

Why extract_section_tool needs a policy

This tool modifies two notes: it removes a section from the original note (replacing it with a wikilink) and creates a new note with that content. Both operations are reversible in principle (the content is preserved, just moved), making this a Write rather than Destructive action.
