dsh-plugin-rankings: Automatically organize DSH plugin ecosystem Top 10 / Top 100 rankings daily

The philosophy of DSH is "everything is a plugin," and the number of plugins in the dsh-plugin ecosystem is continuously growing. Selecting a suitable plugin usually requires manually searching GitHub, browsing community aggregation directories, and comparing npm download counts. Since this information is scattered across multiple channels, there is no direct ranking list available to show which plugins are trending or have high download volumes. The `dsh-plugin-rankings` introduced below is designed to address this issue: it curates Top 10 and Top 100 rankings for the dsh-plugin ecosystem on a daily basis. It supports sorting by popularity (GitHub Stars) or download volume (npm weekly downloads) in descending order, with popularity being the default. The interface is integrated directly into the DSH Web settings page.
