dsh-godot-preview: A Godot 4 Preview Plugin for DeepSeek Harness

DeepSeek Harness (DSH) has released the `dsh-godot-preview` plugin, designed to seamlessly integrate Godot 4 project previewing into AI development sessions and address the frequent need to switch between a terminal and an editor in traditional workflows. The plugin supports standalone installation and offers both Web and Native preview modes. It includes core features such as environment validation, file watching, automatic building, and fallback on failure. By using local process management to ensure security, it requires no modifications to the DSH core and significantly improves debugging efficiency in AI-assisted development.
