feat: integrate offline-package data source

### Changes:

1. **scripts/gen_mirror_manifest.py**
   - Added generation of offline-package.json file
   - Filters listings to only include offline-package directory
   - Writes to the same output directory (dl-index/)

2. **src/lib/download/dl-index-data-offline-package.ts**
   - New module to fetch offline-package data from CDN
   - Fetches from: https://dl.svc.plus/dl-index/offline-package.json
   - Provides helper functions:
     - fetchOfflinePackageListings()
     - getOfflinePackageListings()
     - getOfflinePackageSections()
     - getOfflinePackageFileCount()
   - Includes simple in-memory caching

3. **src/app/download/page.tsx**
   - Updated to use offline-package data
   - Merges offline-package sections with existing data
   - Added offline-package file count to totals
   - Made component async to support data fetching

### Result:
Download page now fetches and displays offline-package data from the CDN endpoint, providing real-time updates without rebuilding the application.
