How it works
A draft is an upsert — if a draft already exists for the same userId + taskId, calling POST
/submissions/draft again updates the content in-place rather than creating a duplicate.
Publishing transitions the draft to PENDING and clears all draft metadata, so it flows into the
existing tutor/AI review pipeline unchanged.
