WHY IT NEEDS A POLICY

Why todoist_label_update needs a policy

Updating a label is a reversible modification that can be undone or corrected. It does not delete data (Destructive), execute code (Execute), move money (Financial), or merely read data (Read). The severity is medium because misuse could alter task organization and metadata for the user or collaborators, but the impact is limited to label configuration and reversible.

From the tool's definition Tool description states 'Update an existing label in Todoist' — this modifies data reversibly. The 'update' verb and the operation on labels (metadata associated with tasks) indicates a non-destructive Write operation.
