dsh-mood-log: Mood Logging and Suggestions

`dsh-mood-log` is a pure Node memory plugin for DeepSeek Harness, designed to record users' emotional states during conversations and generate suggestions. The plugin has no network dependencies and, through the `mood_log` tool, supports logging entries based on mood parameters and returning reference suggestions. Developers can install it using official commands without additional configuration. It is suitable for integration into emotion-aware conversation flows, but its suggestions are for reference only and do not constitute medical advice.
