dsh-nail-trim: Nail Trimming Cycle

DeepSeek Harness (DSH) offers a plugin named `dsh-nail-trim`, designed to address periodic suggestion generation needs through an “everything is a plugin” architecture. The tool is implemented purely in Node.js, has no network dependencies, and supports stable operation in offline environments. Developers can install the plugin by running a specific command and invoke its features directly within a session. The plugin runs with the permissions of the current process, making it suitable for development scenarios that require lightweight helper logic.
