dsh-humidity-comfort: Humidity Comfort Calculation Plugin

dsh-humidity-comfort is a lightweight local computation plugin developed by uckkk for calculating environmental humidity comfort in DeepSeek Harness (DSH). Although classified as an online tool, it has no network dependencies in practice and can return precise computational results through the `humidity_comfort` tool. It is suitable for scenarios requiring local computation while avoiding network requests. Installation requires the `dsh plugin add` command, and you must ensure the Node environment meets the version requirements before use. As a pure Node implementation, it delivers reliable computation while avoiding network latency.
