 Implémenter les tables Drift : Exercise, MediaAsset, Program, ProgramExercise, WorkoutTemplate, WorkoutTemplateProgram, WorkoutTemplateExerciseOverride, ActiveWorkoutSession, ActiveSetResult, ActiveRestState, WorkoutHistory, WorkoutHistorySetResult, change_log. Champs sync-ready sur chaque agrégat : id stable (UUIDv7/ULID), createdAt/updatedAt/deletedAt, schemaVersion, syncState, localRevision, originDeviceId. Voir mémoire projet "gametime-architecture-initial-stack-data-model" pour le détail des champs par entité et les invariants (score = valeur numérique + label/unité snapshotés, exercice jamais supprimé en dur, etc.).
