Add support for selecting multiple books and downloading entire lists, pages, or selections in bulk. This includes long-press actions, a dedicated bulk download queue with retry and cancel support, and format preset configurations.
The commit also simplifies the OPDS random book query using ORDER BY random() and adjusts the Nest dev CLI config to disable the Swagger plugin for faster restarts.
Closes#478
Add the KOReader catalog surfaces, plugin package metadata, and device progress handling needed for the plugin workflow. Keep progress status updates non-blocking so secondary status failures do not reject successful sync writes.
