dsh-couple-talk: A Structured Method for Couple Communication

The dsh-couple-talk plugin in the DSH ecosystem is designed to address the relatively low output quality of general-purpose models in couple communication scenarios by providing a structured communication approach. Maintained by uckkk, it is implemented in pure Node and has no network dependencies. Developers can install it with a single command and require no additional configuration. After installation, calling the registered `couple_talk` tool with scenario parameters returns the corresponding structured communication guide. The plugin runs within the DSH process, so permissions should be considered; it is suitable for scenarios that require structured communication guidance.
