[CONSTITUTIONAL] AIP: ArbOS Version 40 Callisto

We vote for this proposal.

We voted for the measure at the Snapshot vote and continue to support it because EIP-7702 account abstraction and the new BLS12-381 precompiles will materially improve developer flexibility and end-user experience. Timely alignment with Ethereum avoids fragmentation, preserves shared security assumptions, and ensures applications can rely on consistent functionality across layers.
