+Dérivé de la régression CLI/UI signalée le 2026-08-10: les messages process ne s'affichent pas pendant le tour et les usages d'outils MCP (ex. idea_ask_agent) n'apparaissent qu'après terminaison du tool / Final cible. Ticket transverse pour établir un pipeline live des événements conversationnels (progress/tool activity/process) du backend vers l'UI/CLI, sans dépendre du Final.
