dsh-browser-ops: DeepSeek Harness Browser Automation Plugin

`dsh-browser-ops` is a DeepSeek Harness plugin designed to address the limitation that agents cannot operate browsers directly. It provides 27 `browser_*` tools that allow agents to take control of a Chrome browser and perform operations such as taking snapshots, clicking, and filling forms. Its core features include recording manual workflows into JSON with variable slots, supporting parameterized replay to generate test data, and offering a Web GUI panel along with two browser modes: Managed and Connect. It is suitable for scenarios requiring automated browser interaction, reuse of manual workflows, and test data generation, but it does not currently support file uploads, drag-and-drop, or cross-tab operations.
