Module presenter 

Output port for rendering command output

This module defines the Presenter trait, the output port in the hexagonal architecture. A Presenter wraps command execution and controls the output lifecycle. The framework calls present with the command future, and the presenter runs the command, optionally consuming events from its event channel, and returns the command’s result.

Presenter adapters implement this trait to provide different rendering strategies. A stateless adapter renders each event as it arrives; a stateful adapter queries a surface on each render frame. The command’s code is identical regardless of which adapter is in use.
