- Add category field to TelegramChannel (filterable tag like STL, PDF, D&D)
- Category column in channels table with edit via dropdown menu
- Improved creator extraction: filename patterns + channel title fallback
- extractCreatorFromChannelTitle strips [Completed], (Paid), emoji, etc.
- Fix ArchiveType in PackageListItem and PackageRow for new types
- Add Prisma migration for category column
