WHY IT NEEDS A POLICY

Why pin_dialog needs a policy

Pinning/unpinning a dialog modifies the state of the user's chat interface—specifically reordering which conversations appear at the top of the list. This is a reversible Write operation: the user can unpin dialogs to restore previous state. It does not retrieve data (Read), execute code (Execute), permanently delete data (Destructive), or involve financial transactions (Financial).

From the tool's definition The tool name 'pin_dialog' and description 'Закрепить/открепить диалог в шапке списка' (Pin/unpin dialog in the chat list header) indicate modification of user interface state and chat organization metadata.
