v0.1.39-alpha

[0.1.39-alpha] - 2026-07-31

Fixed / 修复

• Stabilized the ESP Meshtastic MQTT session so connection, subscription, and keepalive progress are tracked explicitly through CONNACK, SUBACK, and PINGRESP deadlines; reconnects use bounded exponential backoff, control-plane replies cannot be starved by ordinary Wi-Fi traffic budgets, and inbound QoS 1 publishes are acknowledged with PUBACK. Transient publish failures now retain the in-flight uplink for retry, while a full bounded uplink queue rejects low-priority NodeInfo, position, telemetry, and traceroute reports before they can displace text, control, or encrypted traffic. / 稳定 ESP 端 Meshtastic MQTT 会话：显式跟踪 CONNACK、SUBACK 与 PINGRESP 的连接、订阅和保活时限；重连采用有界指数退避，控制面响应不会再被普通 Wi-Fi 流量预算饿死，入站 QoS 1 发布会正确回复 PUBACK。临时发布失败会保留正在发送的上行消息以便重试；有界上行队列满时，NodeInfo、位置、遥测和 traceroute 等低优先级上报会先被拒绝，不再挤掉文本、控制或加密流量。
