Kobo Library

Runtime skill for search-then-download over the user's Kobo library. Authentication is owned by kobo-auth — this skill assumes auth is ready and exits with a hint if it isn't.

The intended user-facing flow:

1. User describes what they're looking for (title / author / topic / year)
2. Skill resolves filters, queries the library, presents matches as cards
3. User confirms which books to download
4. Skill downloads the chosen RevisionIds (idempotent, DRM-free EPUBs)
