 * block-gas pre-execution checks:
 *
 *   regular check: min(TX_MAX, tx.gas - intrinsicState) > regular_available  → reject
 *   state check:   (tx.gas - intrinsicRegular)         > state_available     → reject

 * When EIP-8037 is not active, returns `{ intrinsicRegular: tx.getIntrinsicGas(),
 * intrinsicState: 0n }` so callers can use a single code path.
