 * Safe to call multiple times — only subscribes once per editor instance.
 *
 * Transactions tagged with `superdoc/block-identity-repair` are exempt:
 * the repair pass rewrites internal block-identity attrs without changing
 * any caller-visible content, so bumping the optimistic-concurrency counter
 * would invalidate a caller's `expectedRevision` for a non-content change.
 * The repair is also non-undoable (`addToHistory: false`) and its emitted
 * AttrSteps carry no `from`/`to` range, so collaborators see it as
 * remediation rather than an edit.
