DeepSeek Harness Sidebar Process Panel Plugin

The DeepSeek Harness plugin `dsh-process-panel` is designed to address the challenges of background process management through a graphical interface. It integrates process operations into the Web sidebar, supporting start, stop, restart, and real-time log viewing, and provides an `sv_*` toolchain for direct control by AI. Users can install the plugin via a command, manage task status intuitively in the GUI, and should be mindful of its dependency version constraints and orphan process handling mechanism.
