Computer-Control DSH Plugin: Desktop Control and Security Protection

The computer-control plugin for DeepSeek Harness (DSH) is designed to provide agents with secure desktop control capabilities, addressing the high risks and limited semantic support of traditional pixel-level operations. Based on the accessibility tree, it provides screenshot, pointer, and keyboard control, and supports semantic actions and batch execution. It includes built-in safety mechanisms and supports dry-run mode. The plugin primarily supports Windows 10/11, interacts with DSH via the JSON-RPC protocol, and allows users to safely take over desktop tasks in a controlled environment.
