Conduit's bare rollup.json for doma-mainnet omits jovian_time entirely, but the
EL genesis activates Jovian at 1769065201. Without the override op-node has no
Jovian fork time and mis-derives at the boundary (chain forks off canonical).
Same fix pattern as bob-sepolia. Override comes from env/op/doma/mainnet/node.env.
