Delete orphaned preview columns

Overview

Deletes every is_preview = true column on the list. Preview columns are created temporarily during the column-preview flow (run enrichment on the first 3 rows before committing) and are normally promoted via PATCH or explicitly cancelled. If a user dismisses the preview dialog without either action, an orphan preview column can be left behind — this endpoint sweeps them. Safe to call on lists with no previews: always returns { success: true } on clean execution. No side effects beyond deleting list_columns rows (and their cells via cascade).

​
AI agent notes

Idempotent. Repeated calls are safe — second call is a no-op.When to call it:
  • On dialog open in the preview flow (the UI does this defensively).
  • As a cleanup step if an agent workflow crashes between column creation and promotion.
Does not affect full columns. Only rows with is_preview = true are deleted. Non-preview columns are untouched.
