dsh-business: Evidence-Driven Business Strategy and Monetization Plugin

`dsh-business` is the pluggable business strategy layer of DeepSeek Harness, designed to decouple general model inference from specific business logic. Positioned as a cross-dimensional “business strategy layer,” the plugin covers the entire process, including strategy formulation, business model analysis, pricing architecture design, profitability analysis, and business handover management, and provides structured decision support and interpretable business models. Before installation, specific dependencies (such as DeepSeek Harness 0.1.5-rc.2) must be satisfied, and it must be installed under the designated profile (for example, `web`) and the process restarted. Its core features include business plan formulation, elevator pitch generation, and business closed-loop review. The plugin only provides decision support and rule validation, not specific execution, making it suitable for embedding business logic into agent workflows.
