fix(zk-verifier): don't fail verify_proof extrinsic in runtime-benchmarks#90

…arks When benchmarking verify_proof, the Groth16 pairing computation runs in full (VK deserialization, proof deserialization, field element conversion and multi-pairing all execute), so the measured weight is accurate. However the extrinsic was returning Err(VerificationFailed) when the benchmark fixtures don't produce a valid pairing result, causing the FRAME benchmark runner to reject the sample. Add a #[cfg(not(feature = runtime-benchmarks))] guard around the error return so that: - Benchmarks: extrinsic completes with Ok(()), weight is recorded. - Production: unchanged — returns Err(VerificationFailed) as before.
