dsh-table-setup: Table Setup and Family Dinner Hosting Plan Generation

The DeepSeek Harness plugin `dsh-table-setup` focuses on family dining scenarios and generates table setups and hosting arrangements. It is implemented purely in Node.js and has no network dependencies. The installation command is `dsh plugin add github:uckkk/dsh-table-setup`, but you must first install `@deepseek-ai/cordis` (^4.0.1) and `@deepseek-ai/dsh-tools` (>=0.1.0-rc.6). Because it runs with the permissions of the current DSH process, we recommend reviewing the source code before installation.
