dsh-jenkins-panel: AI-Invocable Jenkins Tools and Sidebar Panel for DeepSeek Harness

The dsh-jenkins-panel plugin aims to seamlessly integrate Jenkins capabilities into DeepSeek Harness (DSH), addressing the fragmentation between AI and CI/CD tools. Through 22 `jenkins_*` tools and a right-side visualization panel, it enables build triggering, monitoring, log viewing, and automated failure analysis. Developers can manage Jenkins jobs directly in DSH, use AI-assisted investigation to troubleshoot issues, and achieve closed-loop management across the entire build workflow. Installation requires dsh version 0.2.0 or later; explicitly specify the version to avoid compatibility issues.
