CMS Content Extension Seam

Give CMS a generic seam that lets another module attach a richer domain model to a Content — without CMS knowing that model and without extended rows leaking into generic CMS surfaces. Deliver it standalone, exercised by a test-only stub extender, so it ships and is proven before the first real consumer (Modules/Shop Product) exists.
