dsh-ghCLI: GitHub CLI Integration Plugin for DeepSeek Harness

dsh-ghCLI is a gh CLI integration plugin for DeepSeek Harness, designed to address pain points in environment setup and multi-account management. It provides three core capabilities in the DSH settings interface: automatic detection and self-healing for gh CLI (including Windows proxy repair), multi-account authentication management, and high-frequency Git repository operations (such as cloning, pull requests, and forking). The plugin is published as an npm package, installed via `dsh plugin`, and supports absolute-path execution, timeout control for long-running commands, and secure local credential storage.
