bal-devnet-3 spec

:::info :mega: bal-devnet-3 targets to launch 04 March 2026. ::: :::info ❗ EL clients: please add flags to enable/disable BAL optimizations batch/parallel io and parallel execution. ::: :::info ❗ EL clients: EIP-8037 will be using a hardcoded value for the cost per state byte of 1174. This aligns with a block gas limit of 100M, the value being set for the devnet. The cost per state byte value of 1174 will be a treated as a fork constant for this devnet and not depend on the block gas limit. For devnet-4 we will use the full EIP variant where the cpsb will depend on the block gas limit.
