Method apply_pre_execution_changes

crates/execution/flashblocks/src/state_builder.rs:176–205

Applies EIP-4788, EIP-2935, and Canyon create2 deployer pre-execution changes to the EVM. Must be called once per block, before executing any transactions. This mirrors the `apply_pre_execution_changes` behavior of [`base_common_evm::BaseBlockExecutor`] to ensure that the cached execution results match what the validator computes.
