Introduce a per-indexer ratioLimit alongside seedingTimeMinutes to control torrent cleanup. Updates include: documentation (scheduler and settings pages), types and API (saved indexer config now includes ratioLimit), setup and management UI (new TorrentSeedingFields component, modal wiring, validation and handlers), and processor logic (cleanup-seeded-torrents now requires AND-semantics between time and ratio; 0 disables a criterion, both 0 = never cleaned, undefined client ratio with ratioLimit>0 = not met). Tests were added/updated to cover ratio-only, time+ratio, missing-ratio, and UI interactions. Default behavior: ratioLimit defaults to 0 (no ratio requirement).
Introduces 'series' and 'seriesPart' fields to the Audiobook model and database schema. Updates API routes, file organization, and path template utilities to support series metadata. Enhances chapter merging logic, improves notification backend testing, and expands test coverage for admin and API routes.
