dsh-anthropic-membership: Log in to Claude Pro/Max Without an API Key

The `dsh-anthropic-membership` plugin is designed to address the limitations of DeepSeek Harness (DSH) when using Anthropic models. Core features include Pro/Max login without an API Key via OAuth, compressing the long edge of images to 2000px to prevent session freezing, and optimizing the `/compact` command to support a 1 million token context window. After installation, users can log in and manage account status through the UI or command line. The plugin securely writes credentials to the DSH configuration directory and provides a local control interface.
