The current reth fusaka-devnet-2 branch breaks with rbuilder because of breaking changes in revm with eip-7097. This should be resolved by fusaka-devnet-3. We are temporarily using a fork of reth for now.

We ideally need to know which fork we are currently at, in order to create an EIP-4844 type sidecar or EIP-7954 sidecar. We unfortunately don't have this info here.

pool.get_blob wasn't able to retrive the blob in my testing. using pool.get_all_blobs worked in this case.

This PR updates rbuilder to support Fusaka. These changes have been tested locally using Kurtosis
Things to consider in rbuilder:
Breaking changes:
U256representation alloy-rs/nybbles#17 updates the internal representation ofNibblefrom aSmallVec<[u8; 64]>to aU256. This breaks code in the merkle eth sparse tree as the code indexes a lot into theSmallVecrepresentationBlobTransactionSidecarVariantenum which contains PeerDas type blob sidecars too. The only different b/w EIP-7954 sidecars from EIP-4844 sidecars is EIP-7954 sidecars usecell_proofsinstead ofproofs. rbuilder just usesBlobTransactionSidecarwhich breaks with the fulu hard fork.BlockNumberandTimestampto useU256instead ofu64. There are inconsistencies in code where u64 is used for block number which fails to build as a result.CodeSizefield to theAccountInfo. It was previously anOptionbut the mentioned commit makes it a mandatory field.Databasetrait in the alloy/evm repo now implementsstd::fmt::Debugimplemented by alloy-rs/evm@3d6a01b. This broke code since a dependency was using the updatedDatabasetrait from alloy/evm. Using theDatabasetrait from alloy/evm seems to have fixed this.stepmethod has been removed from theaccess_list_inspector.
