DeepSeek Harness Mathematical Modeling Team Plugin Pack

The DeepSeek Harness plugin `dsh-math-team` provides a standardized collaboration framework for mathematical modeling competitions. The plugin includes two types of Agent presets: `model-code` for modeling programming and `paper` for paper writing, supporting multi-person collaboration in independent workspaces via GitHub/Gitee. Core features include quality gates such as M1-M2/P1-P2, particularly M2 robustness attacks, independent dual-model review, and mandatory figure review, ensuring the quality of both the model and the paper. The plugin requires DSH 0.2.0+ and is installed/configured via the `link:` method.
