Delete a message

DELETE

/v1/messages/{id}

• Production

Soft-delete a single outbound message. The payload becomes immediately unreachable; the S3 object is removed by the sweeper on its next run. Metadata and delivery-attempt history are preserved. The original status is kept unchanged.

Idempotent: deleting an already-deleted message returns 200 with already_deleted: true and the original deleted_at timestamp.
