Add PlantGuide iOS app with plant identification and care management
- Implement camera capture and plant identification workflow - Add Core Data persistence for plants, care schedules, and cached API data - Create collection view with grid/list layouts and filtering - Build plant detail views with care information display - Integrate Trefle botanical API for plant care data - Add local image storage for captured plant photos - Implement dependency injection container for testability - Include accessibility support throughout the app Bug fixes in this commit: - Fix Trefle API decoding by removing duplicate CodingKeys - Fix LocalCachedImage to load from correct PlantImages directory - Set dateAdded when saving plants for proper collection sorting Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
