This commit addresses multiple SwiftUI performance bottlenecks identified through code analysis, focusing on view rendering efficiency, list performance, and memory usage optimization. Key improvements: - HomeView: Optimize async task management using structured concurrency with async let to handle multiple Defaults updates in a single task - VideoCell: Remove GeometryReader from VideoCellThumbnail to eliminate layout thrashing; change @ObservedObject to computed property for shared ThumbnailsModel - ThumbnailView: Cache URL extension computation in init() instead of recalculating on every body evaluation - FavoriteItemView: Replace filter().prefix() with early-exit loop and capacity reservation for significant performance gain on large lists - ContentItemView: Optimize FetchRequest creation with direct predicate construction only for video items, empty predicate for others - VideoPlayerView: Fix playerSize didSet trigger by moving updateSidebarQueue() calls to explicit onChange/onAppear handlers - FeedView: Replace .unique() with Set-based deduplication for O(n) performance and reduced allocations - VerticalCells: Remove expensive sorting on every redraw; items should be pre-sorted from source These optimizations follow SwiftUI best practices by minimizing expensive computations in view bodies, caching computed values, using efficient data structures, and avoiding unnecessary redraws and layout passes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
