CreateImportEntity
Track an external item (Linear issue, Notion page, Slack channel) in the import ledger. Use statusstaged to propose an item for import BEFORE creating anything; use status imported (with entityId) only to record a Macro entity you already created from the item. The response tells you when the item was already imported by the user or a teammate — in that case do NOT create a duplicate; point the user at the existing entity instead.
