Allow disabling/remapping the "Ctrl+C twice to exit" behavio

Describe the feature or problem you'd like to solve

Feature request: Allow disabling/remapping the "Ctrl+C twice to exit" behavior. I frequently use Ctrl+C out of habit (from other terminal tools) for two purposes: (1) cancelling an in-progress operation, and (2) copying selected text. In both cases, a second incidental Ctrl+C press exits the CLI entirely and loses my session context. This is especially disruptive since Ctrl+C for copy is a standard OS/terminal convention outside this CLI. Suggest adding a setting (e.g.,  /settings set ctrlCExit false ) to disable exit-on-double-Ctrl+C, keeping Ctrl+C available for cancel/copy, with Ctrl+D remaining as the explicit shutdown key.

Comienza rastreando el manejo de Ctrl+C de la CLI y el comando de settings existente o el punto de entrada de configuración; el issue no especifica archivos ni tests concretos. Confirma cómo interactúan actualmente la cancelación, las pulsaciones de Ctrl+C relacionadas con la copia, la salida mediante una doble pulsación y el apagado con Ctrl+D; después, verifica que el comportamiento pueda deshabilitarse o reasignarse sin eliminar la ruta explícita de apagado.
