Why upload_conference_logo needs a policy

This is a Write operation because it creates or modifies conference data (the logo) reversibly. It is not Destructive because logos can be replaced or removed (delete_conference_logo exists as a separate tool). It is not Execute because it performs a specific data modification, not arbitrary code execution.
