dsh-traffic-light: A desktop traffic light for DeepSeek Harness Session

dsh-traffic-light is a desktop status monitoring plugin designed for DeepSeek Harness (DSH). It aims to address the issue where users must frequently switch back to the DSH page to verify status during parallel processing of multiple Sessions. The plugin generates independent, draggable, and always-on-top floating "traffic lights" on the desktop for monitored Sessions, supporting the simultaneous display of multiple Session statuses. The five page statuses (Idle, Running, Attention, Completed, Failed) are mapped to red, yellow, and green lights for quick identification. The plugin features independent control switches for each Session without interference, and status data is processed locally without uploading any Session content or prompts. Installation requires `web` pro.
