dsh-habit-anchor: Habit Stacking Plugin

The DSH Harness plugin `dsh-habit-anchor` is designed to address the need for a "habit stacking" ritual in agent configuration. Maintained by developer uckkk, its core features include a pure Node.js implementation, no network dependencies, and support for offline generation of habit suggestions returned based on parameters. The installation command is `dsh plugin add github:uckkk/dsh-habit-anchor`. The plugin depends on the `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` environments. It is suitable for developers who need locally generated habit suggestions and provides a lightweight solution for the DSH ecosystem.
