Part 1 of 6-part specification.
Adds L2ProxyAdmin component for batch upgrade orchestration: - Defines upgradePredeploys() function for DELEGATECALL-based batch upgrades - Exclusive Depositor Account authorization - Backwards compatibility with existing ProxyAdmin interface Includes 4 invariants, 3 assumptions, and interface definition.
