What write_zotero_link_note does on Scifinder Route

WHY IT NEEDS A POLICY

Why write_zotero_link_note needs a policy

This tool creates new data (a Zotero note) in an external reference management system. While the operation is reversible (notes can be deleted), it modifies state in a third-party system and could clutter or interfere with a user's Zotero library if invoked inappropriately. The conditional nature ('when endpoint writeback is enabled') slightly mitigates risk.

From the tool's definition Tool name contains 'write_' and description states 'create a Zotero note' which is a reversible write operation to an external system (Zotero).
