dsh-calm: DeepSeek Harness Emotion Checkpoint and Repair Plugin

`dsh-calm` is an emotion checkpoint and repair plugin for DeepSeek Harness. When an Agent encounters insults or noise, it automatically enters calming mode, prevents dangerous operations, and preserves context. Once the user regains composure, it collapses contentious sections and injects a summary, ensuring the task continues from a clean context. The plugin supports automatic session termination, state persistence across restarts, and redacted reads of sealed records. Installation requires Node.js 22.19.0+, offers flexible configuration, and is well suited for enhancing interaction robustness.
