dsh-closet-zone: Closet Zone Plugin

The DeepSeek Harness (DSH) plugin `dsh-closet-zone` is designed to address home storage logic planning. Maintained by developer `uckkk`, it is implemented in pure Node.js with no network dependencies. Its core feature, "closet zoning," generates storage plans based on input parameters. Users can install it via command and directly invoke its registered tool `closet_zone`. The tool runs locally, and users should review its source code and MIT license before installation, empowering DSH agents to handle home storage logic.
