/**
 * MouseMoveTrigger
 *
 * Triggers timelines based on mouse movement:
 * - distance: progress based on distance from center of viewport/target
 * - axis: progress based on X/Y position within viewport/target
 *
 * Supports:
 * - Viewport or custom target element tracking
 * - Optional smoothing (lerp interpolation)
 * - Custom start/leave progress values
 * - Per-element triggers with "each" mode
