dsh-plugin-maker: DeepSeek Harness Plugin Development Workshop

`dsh-plugin-maker` is a toolset designed to reduce the engineering cost of developing DeepSeek Harness plugins. Through features such as scaffold generation, contract validation, health-check remediation, and guided workflows, it automates the fixed specifications of plugin development, helping developers address the compatibility and cognitive overhead introduced by plugin-based architectures. The tool is primarily intended for the development phase and does not involve runtime narrowing or dynamic plugin management; it aims to help users clarify requirements and architecture, rather than blindly generating code.
