Merge 5-weth-bytecode-verification into main   3# Proves the claim the registry exists to make: LOVE lands at the same address
4# on two chains that have nothing about their wETH in common.
6# Two anvil nodes with different chain ids get different wETH implementations,
7# at different addresses — node A the OP Stack predeploy, node B canonical
8# WETH9 at its mainnet address — using the same runtime bytecode the tests
9# etch. Each node is then brought up the way a real chain would be: registry,
10# registration, token. If the two token addresses match, wETH is genuinely out
11# of the creation code.
13# The previous version of this script gave both nodes the same wETH, because
14# back then the address was a constructor argument and matching was only
15# possible when the argument matched. That is exactly what changed.
