Integrate Deterministic Engineering Workflow into DeepSeek Harness with mstar-harness

### 正式翻译（符合技术文档规范）： mstar-harness (Morning Star) is maintained by btspoony, and uses the TypeScript engine to enforce access control for functions such as status/lease/dispatch. The mstar-* skills are responsible for multi-agent delivery judgment. This article verifies the differences between the directory installation command and the dsh plugin --profile web add @mstar-harness/dsh recommended in the README, as well as the usage of `/iteration-start` and `/codebase-audit`, based on the directory page, GitHub README and v2.3.0 release notes. The plugin runs with the permissions of the current dsh process, and you should check the source code and MIT license before installation.
