lexmount/dsh-browser: DeepSeek Harness Browser Automation Tool

`lexmount/dsh-browser` is a lightweight plugin for DeepSeek Harness (DSH) that injects Lexmount cloud browser capabilities into DSH by registering native tools, enabling models to call browser operations directly. The plugin provides 31 native tools covering page diagnostics, authentication, browser operations, and advanced CDP capabilities. Installation requires compatible Node.js and DSH versions and supports Windows, macOS, and Linux platforms. It also features automatic downloading and caching of `browser-cli`, strong security with injection prevention, and offline reuse. Once installed, browser automation can be achieved in DSH through steps such as initialization, authentication, session management, and page operations.
