dsh-shorts-wall: Edge-aligned short video wall in DSH Web

dsh-shorts-wall is a vertical short video plugin designed for the DSH web profile, allowing users to browse YouTube Shorts and Bilibili vertical content directly within the workspace without logging in or opening a new tab. By default, the plugin runs as a vertical sidebar and supports switching to a draggable, resizable floating window or minimized state, with the player not reloading during transitions. It employs a dual-source carousel mechanism to enable free switching between the two platforms; YouTube uses official iframe embedding, while Bilibili uses native MP4 videos combined with a host proxy to support progress scrubbing. The plugin provides various methods for video switching, including the mouse wheel, keyboard shortcuts (e.g., j/k, ↑/↓), and buttons, and features auto-play, bad content skipping, and keyword batch management. Users can maintain preset or custom keyword libraries through the keyword panel, and data is stored independently and persistently.
