dsh-clean-plan2: Generating Home Cleaning Appliance Solutions Based on Parameters

`dsh-clean-plan2` is a lightweight workflow plugin for DeepSeek Harness (DSH), focused on generating household cleaning appliance plans. It does not depend on an external network, is implemented in Node.js, and its core function is to directly return cleaning plans based on input parameters. After installation, users can invoke the `clean_plan2` tool in a conversation. Specific dependency version requirements must be met before use, making it suitable for agent scenarios that provide vertical-domain appliance recommendations.
