Class AbstractEvaaMaster<T>`Abstract`

Abstract base class for EVAA Master contracts

This class provides shared functionality for both Classic and Pyth master implementations, including message creation, validation, and transaction handling. Concrete implementations must override oracle-specific methods for withdraw/liquidation operations.

Implements
