Explain the role of Action in the Model-View-Intent (MVI) architecture.

In the Model-View-Intent (MVI) architecture, an Action represents an event or user intention that initiates a change in the application's state. Action serves as a link between the user interface (View) and the business logic (Model).

When a user interacts with the interface (for example, presses a button), an Action is generated and passed to the handler (Intent). The handler interprets the Action and updates the Model, after which the View is updated based on the new state.

Thus, an Action is a description of what the user wants to do and the first step in the MVI data flow.
