Introducing the DeepSeek Harness Plugin: dsh-rolehub-bridge

`dsh-rolehub-bridge` is a DeepSeek Harness plugin that provides a native compatibility layer for RoleHub, supporting secure loading and validation of roles. It ensures secure role loading through Hub discovery, integrity checks, policy binding, and session management. Installation requires specific Node.js and Harness versions, and the plugin supports refreshing, inspecting, and starting role sessions via the command line or UI. Configuration options can restrict capability sets, and the plugin does not provide model-facing role installation tools. After installation, users can use native controls and Host commands to create sub-sessions while maintaining context independence.
