- Replace per-operation thread spawning with a single persistent
asyncio event loop (saves ~10-50ms per async operation)
- Pre-scan saved directories into sets instead of per-post
exists() calls (~80+ syscalls reduced to a few iterdir())
- Add add_favorites_batch() for single-transaction bulk inserts
- Add missing indexes on favorites.folder and favorites.favorited_at
- Add "Clear cache on exit" checkbox in Settings > Cache
- Fix ugoira zip conversion: don't crash if frames fail, verify gif
exists before deleting zip
- Arrow key past last/first post loads next/prev page
Previously cached .zip files passed the valid media check and were
returned without conversion. Now zips are detected and converted
to GIF before the general cache check.
- Detect .zip files (Pixiv ugoira) and convert frames to animated GIF
- Cache the converted GIF so subsequent loads are instant
- Add filetype field to the info panel
- Add ZIP to valid media magic bytes
