dsh-agent-plugin-bridge: DSH Agent Plugin 1.0 Adapter

`dsh-agent-plugin-bridge` is a universal adapter for DeepSeek Harness, designed to automatically integrate plugins that comply with the Agent Plugin 1.0 specification into the DSH ecosystem. Its core features include automatic scanning and registration, resource injection, environment variable processing, self-diagnostic tools, and version compatibility checks. The plugin supports configuring paths and loading options via a configuration file, must be run in a Node 24 and pnpm 11 environment, and relies on `@deepseek-ai/dsh-tools` to satisfy version requirements.
