Codingendless/dsh-prevent-scd：DSH Sudden Death Prevention Guardian

`dsh-prevent-scd` is a localized plugin for the DeepSeek Harness (DSH) Web UI, designed to prevent users from experiencing excessive fatigue caused by late-night work or prolonged coding and debugging sessions. By monitoring real user input, the plugin detects behaviors such as late-night windows (e.g., 23:00-06:00) or continuous work exceeding a set threshold (e.g., 120 minutes). It then forces the user to rest by displaying a status bar, pop-ups, and full-screen blocking notifications featuring a nurse cat avatar within the browser. Key features of the plugin include: completely offline operation with no external network calls; support for configuring parameters such as work duration, idle time, and late-night hours via `cordis.patch.yml`; state persistence to local files, ensuring effectiveness after service restarts; and the provision of an HTTP interface for polling status or triggering "Take a Break" / "Remind Me Later".
