dsh-cross-team: Cross-Departmental Collaboration Tool

`dsh-cross-team` is a pure Node.js plugin for DeepSeek Harness (DSH), designed to address the need for structured output in multi-department workflow collaboration. It does not rely on network access; it takes input via parameters and returns structured collaboration methods. The plugin depends on the Cordis and DSH Tools environment and is suitable for standardizing cross-department collaboration logic in Agent workflows.
