yoda: copie a la selection vers le presse-papiers, a la Ghostty

La selection n'allait que dans la selection primaire (clic du milieu) ;
pour la coller avec Ctrl+V ailleurs, il fallait Ctrl+Shift+C. Reprise de
copy-on-select = clipboard de Ghostty, le reglage de l'ancienne config
Ghostty de Lionel.

- Config copy_on_select_clipboard (desactive par defaut, comme l'amont) ;
  case dans Reglages > Avance.
- terminal_box::on_selection_done : publie a la fin d'un geste de
  selection fait dans le panneau (glisser, double/triple clic, Shift+
  clic), pas a chaque relachement du bouton gauche. La copie primaire
  existante part elle a tout relachement dans la fenetre : la recopier
  dans le presse-papiers ecraserait, au simple clic sur un onglet, ce
  qu'on vient de copier ailleurs avec une vieille selection.
- Message::SelectionDone : copie la selection de cet onglet ; une
  selection vide (simple clic) ne donne pas de texte (range_simple).
