Implements SGT-aware gas payment for OP Stack chains: - SGT balance reading from predeploy contract (0x4200...0800) - Deduction priority: SGT first, then native balance - Refund priority: native first, then SGT (reverse order) - Full test coverage with op-acceptance-tests - Preserves L1BlockInfo fetch behavior with SGT config Co-authored-by: Claude Code <noreply@anthropic.com>
Move sgt_enabled and sgt_is_native_backed from L1BlockInfo to CfgEnv, accessed via Cfg trait methods (is_sgt_enabled, is_sgt_native_backed). This eliminates the need to: - Mutate the EVM after creation (no configure_sgt on Evm trait) - Preserve/restore SGT flags around L1BlockInfo::try_fetch - Fork alloy-evm SGT config now flows through CfgEnv at EVM creation time, matching how OpSpecId and other hardfork config is passed. Runtime deduction tracking (sgt_native_deducted, sgt_amount_deducted) remains on L1BlockInfo as it is per-transaction mutable state.
