IYieldStrategyManager

Interface for managing external yield strategies.

The IYieldStrategyManager is responsible for routing idle capital from the CapitalPool to external yield protocols (e.g., Aave, Compound). It manages the "Base Yield" component of the system and handles adapter lifecycle management.
