// extract_json_helper — Go-side counterpart to the Rust
// parity_extract_json binary. Reads stdin, runs
// validator.ExtractJSON, prints {matched, value} JSON to stdout.
//
// Used exclusively by
// `scripts/cutover/parity/extract_json_parity.sh` to verify
// cross-runtime equivalence of extract_json across Rust and Go.
