ГЛОБАЛЬНЫЙ РЕФАКТОРИНГ АРХИТЕКТУРЫ - Рефакторинг этапов 2.2 - Усилена оркестрацию в deep/address гейте и follow-up binding в assistantService.ts. Починен кейс UTF-8 follow-up refinement (теперь followup_state_usage.applied=true в нужном сценарии). Убраны регрессии по assistantLivingRouter и stage3 lifecycle probe. Корректное поведение для llm canonical candidate (чтобы не уезжало в clarification_required там, где должен быть address factual).
