 * Hook that handles overlay measurement and positioning during drag start.

 * This hook is responsible for:
 * - Measuring the dragged item's position using measure()
 * - Setting up overlay coordinates relative to the drag container
 * - Calculating the touch offset within the item for proper finger tracking
 * - Setting overlay ready/active flags
 *
 * NOTE: This measure() usage is safe per CLAUDE.md guidelines because:
 * 1. It's only used for INITIAL overlay positioning at drag START
 * 2. It's NOT used for ongoing calculations or drop positioning
 * 3. Drop calculations use index-based math (index * itemHeight) which is reliable
 *
 * @param config - Configuration with containerRef
 * @returns Function to measure and setup overlay
