Register an attachment of the experiment on a host surface Called by the host surface (workflow, content, loop) when a version referencing the experiment is written. One entry per resource however many of its branches (nodes, condition groups) reference the experiment, idempotent on `(surface, resourceId)`: a replay is a no-op. A new attachment needs ready, scheduled or live, unless sourceResourceId names a registered resource of the same surface. Draft and archived experiments cannot receive copies. Once attached, the variant set is locked and back-to-draft / archive are held until every attachment is removed.
