变更项：\n1. 在 markdown_to_image 增加 get_md2img_health_snapshot 健康快照能力，输出 runtime 线程、事件循环、浏览器连接、启动来源与 PID 状态。\n2. 新增系统接口 GET /api/system/md2img_health，支持后台查询转图运行时健康信息。\n3. 新增系统接口 POST /api/system/md2img_warmup，支持后台手动触发转图预热并返回最新状态。\n4. 在资源监控页面接入转图健康状态条，展示运行时在线状态、浏览器连接状态及关键摘要信息。\n5. 在资源监控页面增加转图预热与状态刷新按钮，便于线上快速自愈与排障。\n6. 补充中文注释与错误提示，保持后端与前端可观测性一致。
