dsh-wsl-glab: A Read-Only Status Query Plugin for GitLab CLI

`dsh-wsl-glab` is a GitLab read-only plugin for DeepSeek Harness (DSH), intended to retrieve project context through the `glab` command. It provides core features such as retrieving merge requests, issues, and CI status, supports authentication and timeout configuration, and is query-only, performing no create or merge operations. The plugin requires DSH ≥ 0.1.2, is not included in the suite by default, and is suitable for agents to query GitLab status in write-restricted environments.
