/**
 * BatchValidator — Batch validation of multiple XML files
 * ─────────────────────────────────────────────────────────
 * Validates one or more XML files (or strings) against a schema in one call.
 * Supports parallel execution, progress callbacks, and aggregated reporting.

 * Usage
 * ─────
 *  import { BatchValidator } from 'xml-xsd-engine';
 *
 *  const bv     = new BatchValidator('schema.xsd');
 *  const report = await bv.validateFiles(['a.xml', 'b.xml', 'c.xml']);
 *
 *  console.log(report.summary);
 *  for (const [file, result] of report.results) {
 *    if (!result.valid) console.log(file, result.errors);
 *  }
