Remarks

Subscribe to this event to participate in the runnable lifecycle before state changes occur. When NewValue is false (stopping), this is the ideal place to extract Result before views are disposed and to optionally cancel the stop operation (e.g., prompt to save changes).

This event follows the Terminal.Gui Cancellable Work Pattern (CWP).
