/**
 * BaseTrigger - Abstract base class for all standard trigger types
 *
 * Extracts the common enable/disable lifecycle pattern shared by
 * ScrollTrigger, EventTrigger, MouseMoveTrigger, GestureTrigger, and CursorTrigger.
 *
 * Provides:
 * - enable/disable guards with _enabled flag
 * - DOM-ready gating via whenDOMReady
 * - Shared helper methods for selector resolution and listener cleanup
 *
 * NOT used by PageLoadTrigger (which has a different lifecycle pattern).
