Removes legacy L2OutputOracle (L2OO) proposal logic in favor of exclusive DisputeGameFactory (DGF) support. - Flattened logic in driver.go's loop and sendTransaction. - Removed unused waitForL1Head and manual ABI packing functions. - Updated driver_test.go to remove L2OO test vectors and update DGF mocks. - Cleaned up config_test.go to remove legacy requirement checks. This simplifies the proposer architecture as part of the transition to the Fault Proof system. Fixes ethereum-optimism#18620

There was a problem hiding this comment.
Looks good generally. Couple of small details and we should also remove the L2OO flags.
There are some customised chains still using L2OO support which we'll have to work with before we can merge this though.
