dsh-status-card: Injecting Status Cards into DeepSeek Harness Replies

`dsh-status-card` is a DeepSeek Harness plugin that automatically displays a status card at the beginning of an agent response through system prompt injection, eliminating the need for manually assembling formatting. It supports toggle on/off, custom titles and templates, and includes six built-in styles (A–F), with real-time preview and language adaptation. Installation requires GenUI, settings are persisted, and configuration changes require a new session to take effect.
