 * Creates a directive for tracking pointer position during drag operations.

 * This function sets up event listeners that track pointer movements from an initial pointerdown event
 * through pointermover and pointerup events. It provides a directive that can be attached to DOM elements
 * to enable drag tracking functionality.
 *
 * @param onStart - Callback function invoked when the pointerdown event happens.
 *
 * @returns The pointerdownPositionDirective that can be applied to elements.
 *
 * @example
 * ```typescript
 * const pointerPositionDirective = createPointerdownPositionDirective((event) => {
 *   console.log(`Drag started at (${event.clientX}, ${event.clientY})`);
 *   return {
 *     onMove: (event) => {
 *       console.log(`Dragging: ${event.clientX}, dy=${event.clientY}`);
 *     },
 *     onEnd: () => {
 *       console.log(`Drag ended`);
 *     }
