dsh-deep-equal: A Deep Comparison Tool

dsh-deep-equal is a pure Node.js implementation plugin for DeepSeek Harness (DSH), designed to avoid manually writing deep comparison logic. Maintained by developer uckkk, it provides deep comparison capabilities and can be invoked in sessions. The plugin has no network dependencies, runs with the current process permissions, and depends on `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools`. Install it with `dsh plugin add github:uckkk/dsh-deep-equal`, making it suitable for data diff analysis in DSH.
