Using dsh-director-toolkit to break rough 3D ideas into actionable shot lists

### 正式翻译（适配技术文档语境）： dsh-director-toolkit is a development and runtime plugin for DeepSeek Harness maintained by lhmd. Instead of directly generating meshes, it breaks half-formed 3D concepts into shot lists, lighting setups, material guidelines, software-specific rendering suggestions, and a five-step production checklist, then outputs directional packages compatible with Blender, Three.js, Houdini or C4D. The local version of scene_director does not require an API key; the optional scene_director_v4 calls deepseek-v4-pro by default. The directory installation command is `dsh plugin add github:lhmd/dsh-director-toolkit`.
