dsh-plugin-judge: DSH Plugin Value Judge

`dsh-plugin-judge` is a plugin value judgment tool in the DeepSeek Harness ecosystem, designed to address the issue that a plugin's value can fluctuate with model changes. It provides three core capabilities: pre-installation review (static scanning + LLM judgment), post-installation audit (risk scoring), and reminders for re-evaluation when switching models. Through commands or the settings panel, users can assess plugin suitability and manage constraint-related risks, ensuring that plugins do not impair task performance due to rule restrictions or model upgrades. Installation requires environment prerequisites such as Node.js >= 18; judgment results are for reference only, so install third-party code cautiously.
