dsh-dry-guide: Air-Drying and Tumble-Drying Guide

The `dsh-dry-guide` released by DeepSeek Harness (DSH) is a local plugin implemented in pure Node.js and maintained by uckkk. It registers the `dry_guide` tool, so after users provide parameters, it directly returns specific drying recommendations without requiring an internet connection. The plugin runs with DSH process privileges. The installation command is `dsh plugin add github:uckkk/dsh-dry-guide`, and it is recommended to review the source code and license before use.
