/triage (sélecteur par taille de backlog) + /triage/{o}/{r}
(session plein cadre, file embarquée): 1-5 colonnes, X fermer,
L étiquettes, A s'assigner (nouvel endpoint assign-self +
client.set_issue_assignees, idempotent), Entrée suivante, Z annuler.
Progression + résumé de session; décisions via /api/move et les
API existantes. Entrées: board + palette.
