Why todoist_duplicates_merge needs a policy

While the tool performs modifications to tasks (completing or deleting), the primary intent is reversible state changes (task completion can be undone, and deletion in Todoist typically moves to trash). The tool is designed for cleanup rather than permanent destruction. This is categorized as Write rather than Destructive because Todoist task deletion is generally recoverable via trash/undo.

From the tool's definition Tool description states: 'Merge duplicate tasks by keeping one task and completing or deleting the others.' The operations of completing or deleting tasks are write/destructive modifications to task state.
