dsh-deepseek-web-entry: Add a shortcut to the DeepSeek web version in the Harness left sidebar

dsh-deepseek-web-entry is a client plugin maintained by Mystery-W that adds a "DeepSeek Web Version" entry at the bottom of the DeepSeek Harness left sidebar: the main button expands/collapses the built-in browser on the right and opens chat.deepseek.com, while the small button ↗ opens the same address in the system default browser to reuse the existing login session. The plugin only provides an entry point; it does not proxy web pages, inject scripts, auto-login, or consume API credits. It is unrelated to Marisa, written in pure JavaScript, requires no build steps, has zero dependencies, is under the MIT license, and requires Node >= 20. The article verified the installation method in the README (installing from a local directory or URL via the plugin management page, without the `dsh plugin add` command), file responsibilities, Cordis patch, client-side dependency on `@deepseek-ai/dsh-client-ui-sidebar-right`, the offline self-check command `node selfcheck-client.mjs`, and the four limitations listed in the README: an embedded Electron webview may be flagged as an environment anomaly, login state cannot be reused from Harness, cookies are not preserved across restarts, and it is an unofficial product. Regarding security, the open-external route only accepts the hardcoded chat.deepseek.com address. It is recommended to check the source code and license before installation; SkillHub is an independent community site with no official affiliation with DeepSeek.
