- BookMatch now carries title/author/cover (the fields the old client
renderer always assumed but the API never sent — cards would have
shown 'undefined'); filled during the family-lens pass in QueryBooks
- new partial route GET /unlinked-books/matches renders the scoped
match cascade server-side; searchMatches swaps it via htmx.ajax
instead of rebuilding cards from JSON
- NOTE: the unlinked-books surface is currently dark end-to-end — the
templ page has no route, the live linking.ts renderer targets a
container no template has, and its Link button calls a
window.showMatchModal that does not exist. This commit ships the
scoped backend + partial; wiring the UI is a product decision.
