Introduce a per-user "ignored audiobooks" feature to suppress auto-requests. Changes include:
- Database: add Prisma model IgnoredAudiobook and SQL migration to create ignored_audiobooks table with indexes and FK to users.
- Backend: new API routes to list, add, delete, and check ignored audiobooks (/api/user/ignored-audiobooks, /check/:asin, /:id). Add annotateWithIgnoreStatus utility and integrate it into multiple audiobook list endpoints (popular, new-releases, category, search, authors, series).
- Request creator: add ignore-list check (with sibling-ASIN expansion) and a bypassIgnore option for manual requests; return an 'ignored' reason when blocked.
- Frontend: hooks (useIsIgnored, useToggleIgnore, useIgnoredList) and UI updates — AudiobookCard shows an "Ignored" indicator and AudiobookDetailsModal adds an ignore toggle and propagates local state changes.
- Misc: adjust deduplication duration tolerance (to 5% / min 10 minutes), tweak SWR refresh intervals for shelves/syncing, and small logging/info updates.
- Tests: add unit tests for request-creator ignore logic and update existing tests/mocks to account for ignore annotation; extend prisma test helper with ignoredAudiobook mock.
This commit implements the ignore-list end-to-end (DB, server, client, and tests) so users can ignore specific ASINs and have auto-request flows respect that preference.
Add persistent cross-ASIN "works" mapping and client-side deduplication to improve library matching. Introduces a Prisma migration and models (Work, WorkAsin) plus src/lib/services/works.service for persisting dedup groups, seeding ASINs at request time, and sibling lookup. Adds a deduplication utility (deduplicate-audiobooks) that normalizes titles/narrators, compares durations, and returns grouping metadata; API routes (search, author, series) now deduplicate results before enrichment and fire-and-forget persist groups. Adds sibling-ASIN expansion into audiobook matcher and expands getAvailableAsins accordingly. Extracts runtime parsing into a shared parse-runtime util and updates audible scrapers/services to use it. Includes unit tests for dedup logic and works service and updates test Prisma mocks.
Replaces scattered console statements with a unified RMABLogger across backend API routes and services. Adds LOG_LEVEL-based filtering, job-aware database persistence, and context-based logging. Updates documentation to describe the new logging system and usage patterns. Also documents qBittorrent CSRF header fix
