/**
 * Creates a registry of resolved cards, for use with editor actions.
 * Registration changes (insertion, deletion, and id/title/url updates) notify subscribers; live position changes do not.
 *
 * @returns A registry object with the following methods:
 * - `getCardRegistrations`: Returns the current registrations, keyed by card ID.
 * - `registerCard`: Adds or updates a card.
 * - `removeCard`: Removes a card by ID.
 * - `subscribe`: Registers a change listener and returns an unsubscribe function.
