dsh-research: A Research Plugin Marketplace in DSH Settings

dsh-research is an independent research plugin marketplace designed to address the fragmentation of tools for literature search, reference management, and writing review. The plugin adds a "Research plugins" page to the DSH settings sidebar, showcasing curated research tools, and uses a single shared market.json to ensure consistency between the settings panel and the browser directory (dsh-research.com/plugins), preventing data drift. Users can install plugins directly to the currently running profile via the Install button on the page, without needing to manually enter commands. To ensure security and stability, installation behavior is strictly constrained: only packages on the whitelist may be installed, cross-origin triggering is restricted, concurrent writes are prevented to avoid conflicts, and installation targets strictly follow the profile parameters specified at host startup.
