dsh-hotel-tax: Hotel Tax Calculation

The `dsh-hotel-tax` plugin is maintained by uckkk and specifically designed for the DeepSeek Harness ecosystem to address the complexity and error-prone nature of hotel booking tax calculations. Implemented in pure Node.js, it accurately calculates taxes based on parameters and returns detailed results without any network requests. The installation command is `dsh plugin add github:uckkk/dsh-hotel-tax`. It requires the runtime dependencies `@deepseek-ai/cordis` (^4.0.1) and `@deepseek-ai/dsh-tools` (>=0.1.0-rc.6), and is licensed under the MIT License. It provides agents with a standardized tax calculation interface that can be called directly in DSH sessions.
