dsh-model-palette: DeepSeek Harness Global Model Command Palette

dsh-model-palette is a global model selection and configuration plugin designed for DeepSeek Harness, intended to simplify switching among models from multiple providers. By invoking the command palette with the `Alt+M` shortcut, users can quickly select models using fuzzy search, a provider sidebar, and built-in presets for 469 authoritative models. The plugin also supports reasoning effort selection, model template configuration, and optional OpenRouter media tools. From a security perspective, it stores masked API keys in a local service and enforces CSRF protection, ensuring credentials are accessible only in the local loopback environment. The installation command is `dsh plugin --profile web add github:Jensen-Yao/dsh-model-palette#v0.12.0`.
