Copier-coller dans le terminal, et suite de tests versionnee
Le terminal n'avait aucun copier-coller : impossible de selectionner du texte a la souris ni de coller une commande. C'est la fonction la plus basique d'un terminal et de loin le manque le plus penible a l'usage. - selection a la souris avec surlignage, suivant le theme actif - double-clic : selectionne le mot sous le curseur - Ctrl+Shift+C / Ctrl+Shift+V, Maj+Inser, clic molette, menu au clic droit - Ctrl+C reste l'interruption : les raccourcis du presse-papiers sont traites avant la conversion Ctrl+lettre, sinon Ctrl+Shift+C serait parti comme un Ctrl+C vers le shell - au collage, les fins de ligne sont normalisees en retour chariot ; un \r\n enverrait une ligne vide supplementaire au shell La suite de tests vivait dans un dossier temporaire et aurait ete perdue : elle rejoint le depot dans tests/ avec un lanceur. Elle couvre le presse-papiers, la detection d'hote, la logique SFTP sur serveur simule et la construction de l'application. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
