Initial commit: SimVision tvOS streaming app

Features:
- VOD library with movie grouping and version detection
- TV show library with season/episode organization
- TMDB integration for trending shows and recently aired episodes
- Recent releases section with TMDB release date sorting
- Watch history tracking with continue watching
- Playlist caching (12-hour TTL) for offline support
- M3U playlist parsing with XStream API support
- Authentication with credential storage

Technical:
- SwiftUI for tvOS
- Actor-based services for thread safety
- Persistent caching for playlists, TMDB data, and watch history
- KSPlayer integration for video playback
