/**
 * Hook to manage drag-to-resize functionality.
 * Uses direct DOM manipulation during drag for smooth performance.
 *
 * Double-click detection:
 * - Native `dblclick` events don't fire reliably with `preventDefault()` on `pointerdown`
 * - Instead, we track timestamps: if two `pointerdown` events occur within DOUBLE_CLICK_THRESHOLD, it's a double-click
 * - On double-click, dimensions reset to defaults, `onResize` is called to persist, then `onReset` for cleanup
 * - We also track `hasMovedRef` to avoid persisting on click-without-drag (allows clean double-click UX)
