JeremiahM37/librarr ? reverse-engineered prompt

Build me a self hosted app for managing books, audiobooks, and manga, kind of like Sonarr or Radarr but for a reading library.

I want to be able to search across multiple sources at once, see the best matches ranked by confidence, and then download or import items into my library automatically. It should support a request flow too, so regular users can request a book and an admin can approve it before anything gets downloaded.

Please include a clean web interface for browsing the library, wishlist, search results, and settings, plus support for multiple users, login, and basic security like 2FA. It should also work with Calibre, Audiobookshelf, Kavita, and Komga, and have an OPDS feed and a Torznab style API so other apps can talk to it.

If possible, make it easy to run in Docker or as a single Go binary, and keep it lightweight. If you need current docs for any library or integration, look them up online.
