Introduce manual import workflow and download permission support. Adds a Prisma migration and schema field (users.download_access) to track per-user download access, and updates admin UI to toggle global and per-user download access. Implements new APIs: filesystem browse, manual-import endpoint, download-access settings, audiobook download-status, and on-demand download-token generation. Adds frontend components for manual import and related tests, plus documentation for the manual-import feature and the documentation-agent prompt. Key files: prisma/migrations/20260212000000_add_download_access_permission/migration.sql, prisma/schema.prisma, src/app/api/admin/filesystem/browse/route.ts, src/app/api/admin/manual-import/route.ts, src/app/api/admin/settings/download-access/route.ts, src/app/api/requests/[id]/download-token/route.ts, src/app/api/audiobooks/[asin]/download-status/route.ts, and updated admin users pages/components and permissions util.
- jwt.ts: Use JWT_DOWNLOAD_SECRET instead of JWT_SECRET for download tokens
- audio-formats.ts: Add EBOOK_EXTENSIONS export alongside AUDIO_EXTENSIONS
- request-statuses.ts: New shared COMPLETED_STATUSES constant used across requests API, download route, and RequestCard
- requests/route.ts: Import COMPLETED_STATUSES; strip filePath from audiobook in API response
- download/route.ts: Import format/status constants; add archiver dependency and replace adm-zip with streaming archiver for multi-file zips
- RequestCard.tsx: Use shared COMPLETED_STATUSES constant
Embeds a signed JWT download token (30-day expiry) in the requests API
response so users can download completed audiobook/ebook files directly
from the UI or by sharing the URL to apps like BookPlayer — no session
cookie required.
- jwt.ts: add generateDownloadToken / verifyDownloadToken helpers
- api/requests: append downloadUrl to completed requests with a filePath
- api/requests/[id]/download: new token-authenticated streaming endpoint;
serves single files directly or zips multi-file audiobooks with adm-zip
- RequestCard: add Download link in the actions area for completed requests
