[Constitutional] AIP: Update the Upgrade Executors

We vote in favor of this proposal.

This streamlines Arbitrum’s upgrade execution by introducing a direct-call method (executeCall()), thus reducing the complexity and potential risks associated with delegate calls and single-use upgrade contracts. Maintaining existing permission structures ensures continuity of trust assumptions while enhancing operational efficiency. Additionally, the upgrade mitigates technical overhead, benefiting both developers and the broader community through clearer and safer upgrade processes.

That said, as many other delegates pointed out, the audit status should’ve been disclosed prior to the vote, considering the importance of transparency for the DAO to effectively manage contracts in a secure manner.
