v1.0.0-beta (Jellyfin Plugin)

fix(jellyfin): replace internal API usage for compatibility with 10.10+

Root cause: Jellyfin 10.10+ made InternalItemsQuery internal and changed TaskTriggerInfo.TriggerDaily constant.

Fixes:
- Replace InternalItemsQuery with _libraryManager.RootFolder.GetRecursiveChildren
- Change TaskTriggerInfo.TriggerDaily to TaskTriggerInfoType.DailyTrigger
