- Pre-BAL path keeps StateDB synchronous read-time accumulators (AccountReads, StorageReads, CodeReads, CodeLoaded, CodeLoadBytes) so Execution = ptime - reads stays well-formed under single-thread execution. - BAL path drops aggregate reader read-times; under parallel workers they sum across goroutines and aren't a wall-clock proxy. - Delete dead PrefetchReadTimes/WaitPrefetch forwarders on *reader and the now-unused ReadTimer/ReadDurations scaffolding. - Add regression test for EIP-7702 delegation clear: empty []byte code in the BAL must reset CodeHash to EmptyCodeHash.
