WHY IT NEEDS A POLICY

Why collect_article needs a policy

This tool saves/bookmarks an article to the user's collection on Juejin. It creates a new association (favorite/bookmark) which is a reversible write operation. It does not delete data, execute code, or involve financial transactions. The authorization requirement indicates it acts on behalf of a user account, raising the blast radius slightly if misused to spam collections.

From the tool's definition 收藏文章（需要授权）— 'collect article' (requires authorization); bookmarking/favoriting an article creates a new saved record
