Add a new scenario that exercises the granular gas accounting paths introduced by EIP-2780. Includes 8 modes targeting specific gas paths: - new-account: value transfer to fresh address (GAS_NEW_ACCOUNT) - precompile: value transfer to 0x01-0x09 (warm precompiles) - access-list: value transfer with recipient in access list - contract-call: call deployed contract (COLD_ACCOUNT_COST_CODE) - value-call: contract forwards ETH to existing EOA (CALL_VALUE_COST) - value-call-new: contract forwards ETH to fresh address - selfdestruct: create child + selfdestruct in same tx (EIP-6780) - all (default): cycles through all modes round-robin Includes EIP2780Helper.sol contract with nop(), forwardValue(), and createAndDestroy() functions, plus generated Go bindings via abigen.
