dsh-plugin-list-plus: Enhanced Plugin List for DeepSeek Harness Web Settings

dsh-plugin-list-plus is an enhanced plugin management tool for DeepSeek Harness, designed to address the lack of information in the default view. The plugin presents plugin sources in a tiered hierarchy (official, organization, and personal), and supports collapsible groups, card-style detail display, and search filtering. It uses an architecture that separates Node-side data fetching from browser-side rendering, and runs as a standalone tab to help developers clearly identify plugin sources and manage configuration state.
