Mirrors luxcpp/cevm lib/evm/state/bench_state.cpp exactly — same N, same
address derivation, same pre-funding, timing the transfers plus the state
root — so the C++ and Go numbers are comparable on one machine.
The C++ bench previously printed a hardcoded "luxfi/geth StateDB: 62.31 ms"
captured on another box. Re-measuring both here (M1 Max) puts geth at
146.33 ms vs cevm 37.28 ms, so the baked constant understated the gap by
more than 2x. That constant is now removed in favour of this benchmark.
