+Symptome utilisateur: dans un autre projet, une delegation Main -> Git via idea_ask_agent renvoie soit une reponse sur un autre depot, soit 'finished without a structured Final response'. La meme demande executee directement dans la cellule Git fonctionne. Suspicion forte: bug specifique au chemin OpenCode headless (reattache/session/cwd/contexte projet) et/ou a la capture de Final OpenCode. Objectif: verifier si le bug est bien specifique a OpenCode, identifier la cause, corriger, puis valider par test.
