/**
 * Legacy streaming compatibility wrapper.
 *
 * Kept for historical reasons; the original implementation relied on a
 * `.stream()` method on the Parser class that has since been removed, so in
 * practice this shim does not produce events today. It is preserved as an
 * entry point in case a streaming wrapper is reintroduced, and to keep the
 * file/export surface stable across the TypeScript migration.
