🧠 feat(orquestrador): fortalecer contexto multiassunto e gestão de revisão

- unifica plano de mensagem via LLM (roteamento + entidades por pedido)
- adiciona fallback de extração separada apenas quando o plano vier sem dados úteis
- reduz reprocessamento no mesmo turno com fila explícita e avanço por 'continuar'
- melhora UX de fila com aviso determinístico de pedidos enfileirados
- amplia intents de revisão: listagem, cancelamento e remarcação
- adiciona campos dedicados para gestão de revisão (protocolo, nova_data_hora, motivo)
- implementa slot filling para cancelar/remarcar revisão com prompts de faltantes
- reforça regras de troca de contexto quando há fluxo de revisão aberto
- adiciona memória curta do último pacote de revisão com TTL (20 min)
- implementa confirmação de reuso de pacote para novo agendamento
- quando reuso confirmado, coleta apenas data/hora e mantém demais dados
- preserva arquitetura: LLM decide e extrai; sistema normaliza, valida, mantém estado e executa tools

✅ Benefícios:
- maior robustez em cenários ambíguos de revisão
- melhor continuidade entre assuntos sem perder contexto
- menor atrito no reagendamento de revisões semelhantes
