dsh-model-jury: Structured Cross-Model Peer Review for DeepSeek Harness

`dsh-model-jury` is a plugin for DeepSeek Harness designed to resolve inconsistent outputs and the lack of objective review in multi-model collaboration through a structured cross-model peer review mechanism. Featuring blind review, anonymous peer evaluation, and a revision stage, it uses code logic—rather than a specific model acting as judge—to make deterministic rulings, thereby enabling decentralized review. Users can configure providers such as GLM and DeepSeek via a configuration file and use the `/jury` command to initiate reviews in either standard or adversarial styles, making it suitable for scenarios such as cross-validating technical solutions.
