/**
 * ParseBudget — Phase 13: Parsing cost tracking + timeout
 * ─────────────────────────────────────────────────────────
 * Provides a configurable "budget" that can abort parsing when any of
 * these limits is exceeded:
 *
 *   • wallTime   – maximum elapsed milliseconds
 *   • bytes      – maximum input bytes processed
 *   • nodes      – maximum DOM nodes created
 *   • depth      – maximum nesting depth  (also in ParseOptions)
 *
 * Usage
 * ─────
 *  const budget = new ParseBudget({ wallTimeMs: 2000, nodes: 500_000 });
 *  const doc = budget.parse(hugeXml);    // throws XmlError(SEC_*) if exceeded
