Equip DeepSeek Harness with an ADHD behavior coach using dsh-adhd-copilot

### 正式翻译版本（符合海外技术文档表述习惯）： The `dsh-adhd-copilot` is a DeepSeek Harness skill plugin maintained by zimai233, targeted at scenarios where ADHD users get stuck in executive functioning: it scans for symptoms including difficulty initiating tasks, overwhelm, distraction, time misestimation, low motivation, and self-blame, and routes interventions to M1–M8 following the priority order of *emotion > structure > initiation*, providing only 1 to 3 actionable minimal steps per session. This article verifies the installation command, usage of `adhd_breakdown`, safety boundaries and precautions against the community directory page and GitHub repository. It is licensed under MIT, and it is currently recommended to install from GitHub and pin the commit hash.
