chore(repo): initialise le dépôt git et l'état de configuration IdeA

Ajoute le .gitignore Flutter/Dart standard (build/, .dart_tool/, Pods,
gradle, etc.) en prévision du scaffolding Flutter (ticket #2), ainsi que
la configuration d'orchestration IdeA (agents, mémoire, tickets, sprints).
L'état d'exécution transitoire (conversations, run/, live-state) reste
ignoré du versionnement.
