+/**
+ * 规则引擎：匹配源主题过滤器后，将消息转发到外部 Broker（桥接到 EMQX）
+ *
+ * 规则表 wxapp_mqttbroker_rule：
+ *   source_filter  源主题过滤器（支持 + / #）
+ *   target_type    mqtt（当前仅支持转发到外部 MQTT Broker）
+ *   target_broker  外部地址 host:port
+ *   target_topic   目标主题模板，支持 ${topic} 变量
+ *   target_qos     转发 QoS
+ *   enabled        1启用 0停用
+ *
+ * 行为：
+ *   - 仅对本地产生的消息生效（distribute 本地路径调用），桥接/外部回流消息不二次转发，避免回环。
+ *   - $SYS 系统主题不转发。
+ *   - 规则带 30s TTL 缓存，新增/修改后最多 30s 生效。
