/**
 * Public entry point for the OOXML validator.
 *
 * Validates an xlsx package buffer against the OPC spec and Excel's
 * known opening invariants. See `types.ts` for the full catalog of
 * problem kinds.
 *
 * ```ts
 * const report = await validateXlsxBuffer(await wb.xlsx.writeBuffer());
 * if (!report.ok) {
 *   console.error(report.problems);
 * }
 * ```
 *
 * The implementation is composed of independent checkers under
 * `check-*.ts` — each can be unit-tested in isolation. The entry point
 * orchestrates them with a shared `ValidationContext` that caches XML
 * parsing across checks.
