dsh-hair-care: Hair Care Tips

The `dsh-hair-care` plugin for DeepSeek Harness (DSH) provides hair care advisory features. Maintained by uckkk, it supports returning specific care routines via the `hair_care` tool based on the provided parameters. Built entirely in Node.js, it requires no network dependencies. Users can install it via `dsh plugin add github:uckkk/dsh-hair-care` and directly invoke the tool in a session to obtain lightweight hair care suggestions.
