/**
 * EventDelegator
 * ----------------
 * A root-scoped, service-style event delegation primitive.
 *
 * Core characteristics:
 * - Single attachment point (root)
 * - Cached native listeners per (eventType + options)
 * - Internal routing table for selectors and handlers
 * - Service lifecycle control (start / stop / pause / resume)
 * - Optional host for environment tooling (no globals)
 * - Pluggable error handling policy
 * - Taggable handlers for SPA / stateful teardown
 *
 * Design goals:
 * - Minimal surface area
 * - No implicit globals or auto-negotiation
 * - BYOB (bring your own root / environment)
 * - Predictable teardown and rebinding
 * - Introspection-friendly (for monitoring / custom consoles)
 *
 * This module does NOT:
 * - Bind per-element listeners
 * - Query the DOM at registration time
 * - Manage application state
 *
 * Delegation model:
 * - One native listener per (eventType + optionsKey)
 * - All handler dispatch resolved at event time
 *
 * Intended usage:
 * - Browser DOM event delegation
 * - SPA page/module lifecycle management
 * - Embedded or sandboxed DOM environments
