全栈更新管理：对 DeepSeek Harness 主程序与每个已装第三方插件做 npm/GitHub 双源 semver 比对，GUI 横幅随系统语言（中/英）提示可更新插件；一键更新主程序或任意插件，自动备份可回滚，更新后看门狗自动重启服务。Whole-stack update management for DeepSeek Harness: dual-source semver checks of the main program and every third-party plugin, a locale-aware banner, one-click updates with backup/rollback and watchdog-guarded restart.
DeepSeek Harness watchdog plugin: detects truly stalled agent turns (never killing in-progress tasks — in-flight operations are exempt), nudges/terminates only on real silence, records every event to JSONL with a loopback status route
DeepSeek Harness task-protection plugin: preflight scanner (catches missing inject declarations that crash the host), loop detection, recursion guard, and interruption awareness with a safe-restart helper. Never terminates tasks.
