feat: Alt+/ autocomplete + auto-continue listes/checkboxes au Enter

- Raccourci: Ctrl+Space → Alt+/ (evite conflit OS)
- Enter sur ligne liste (-, *, +) → continue la puce
- Enter sur ligne vide (puce sans texte) → termine la liste
- Enter sur liste numerotee (1.) → auto-incremente (2.)
- Enter sur checkbox (- [ ]) → nouvelle checkbox vide
- Aide F1 mise a jour, barre statut mise a jour
