dsh-codebuddy-cli: Reusing the CodeBuddy CLI Login Session to Access Models

`dsh-codebuddy-cli` is a DeepSeek Harness plugin designed to reuse the CodeBuddy CLI login session and integrate models such as GLM-5.3 into DSH. After installation, users can directly use CodeBuddy models in the DSH chat window without additional configuration. The plugin supports multi-account management, credit multiplier display, daily check-in, image input, and adjustable thinking intensity. Before installing, ensure that CodeBuddy CLI is installed and logged in, and that the DSH version is 0.1.2-rc.1 or later. TUI users should defer installation.
