 * BulkDuplicateCommand - Duplicate multiple entities at once

 * Wraps multiple DuplicateEntityCommand instances into a single bulk operation.
 * Applies smart grid-based offsets to prevent entities from spawning on top of each other.
 *
 * @example
 * const bulkDuplicate = new BulkDuplicateCommand(ctx, [eid1, eid2, eid3]);
 * commandManager.execute(bulkDuplicate);
 * // All entities duplicated with grid spacing, single undo removes all
