dsh-scent-pick: Scent Scenario Selection

`dsh-scent-pick` is a playful dress-up-style plugin for DeepSeek Harness (DSH), implemented purely in Node.js, that returns fragrance oil recommendations based on scene parameters. It works offline and can be installed with the command `dsh plugin add github:uckkk/dsh-scent-pick`. After installation, it registers the core `scent_pick` tool, helping agents quickly retrieve scene-based fragrance configurations. Because it runs with the current process permissions, users are advised to review the source code and license (MIT) before installing.
