Find unfinished series

Read ../books-library/SKILL.md first to choose the authoritative backend, then read ../books-library/references/series.md.

Find series with at least one read book and at least one unread book. Use the selected backend's helper rather than writing an ad hoc parser: the Calibre books-find-incomplete-series skill and the Goodreads GoodreadsLibrary helper. Sort series by name and identify the first unread book in series order only when the source provides a usable series index.

Report each series' read/total count and next title, author, series index, page count, and rating when available. State when no unfinished series are found and label unknown fields instead of guessing.
