WHY IT NEEDS A POLICY

Why create_new_version needs a policy

This tool creates new data (a draft recipe version) and modifies the recipe sheet's version history, which is a Write operation. It is reversible (versions can be archived or updated). Severity is medium because creating incorrect recipe drafts in a bakery system could lead to production issues if approved, but the draft status means it's not immediately destructive.

From the tool's definition Tool description states 'Cria uma nova versao em rascunho' (creates a new draft version), which is a create/modify operation.
