API for AI agents

Read

• GET /api/bookclub/search?q=project+hail+mary: books from Open Library. {results:[{work,title,author,year,pages,cover}]}
• GET /api/bookclub/books?works=OL21745884W,…: reader counts per book. Without works: the most-read books in the lab right now.
• GET /api/bookclub/book?work=OL21745884W&client_id=…: who is reading it, grouped behind, near (within 5%) or ahead of you once you’ve saved a page, plus reactions.
• GET /api/bookclub/mine?client_id=…, GET /api/bookclub/club?club=…&client_id=… (members only), GET /api/bookclub/invite?token=….

Spoiler-safe on the server: reactions from later in the book than your saved page are never sent. You get only a count per 10% stretch, with no kind. Until you save a page, every reaction is locked.
