WHY IT NEEDS A POLICY

Why apply_text_style needs a policy

This tool modifies existing text properties (font, size, color, formatting, etc.) within an Illustrator document. While changes are reversible (styling can be changed again), they alter document state and could affect design work. This qualifies as Write rather than Read (which would only inspect) or Execute (which would run code).

From the tool's definition Tool applies text styling to text elements, modifying document content. The description states it 'apply[s]' styling, which is a reversible modification operation.
