Add works table and ASIN deduping

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.
