- Configure dependencies: drift 2.32.x, flutter_riverpod 3.3.1, fl_chart 1.2.x, flutter_local_notifications 21.x, local_auth 3.x, and supporting packages - Drop riverpod_generator (incompatible analyzer version with drift_dev 2.32.x); convert all providers to manual Riverpod 3.x API using Notifier<T> and typed families - Define drift schema: MoodEntries, Activities, EntryActivities, Tags, EntryTags, LlmInsights, UserSettings with four DAOs (mood, activity, insight, settings) - Add LLM service abstraction (LlmService) and MediaPipe implementation - Fix SettingsDao.delete → deleteByKey to avoid shadowing drift's inherited delete method
