dsh-pc-pilot: A Windows Desktop and Browser Automation Plugin

`dsh-pc-pilot` is a DeepSeek Harness plugin running on Windows 10/11 that provides agents with integrated local desktop and browser operation capabilities. By leveraging the UIA accessibility tree, background synthetic input, and persistent Chromium CDP sessions, it addresses the issues of traditional automation stealing focus and obscuring windows. The plugin supports application and window management, basic interactions, and browser navigation, with advanced features such as identity recognition, state restoration, and batch execution. It runs with the current process permissions, does not support virtual machines or hidden sessions, and is designed to provide a secure and stable foundation for agent environment operations.
