Add HealthBridge iOS app for intelligent health data synchronization

Complete implementation of a SwiftUI iOS app that serves as a "Single Source of Truth" for health data. The app reads from all Apple Health sources, detects conflicts between devices, merges data using configurable strategies, and writes cleaned data back. Features: - Phase 1: HealthKit integration with automatic source discovery - Phase 2: DataReader with conflict detection (time-window based) - Phase 3: RuleEngine with 8 merge strategies (exclusive, priority, higher wins, etc.) - Phase 4: MergeEngine for conflict resolution + DataWriter for HealthKit writes - Phase 5: SwiftUI UI for dashboard, conflicts, rules, and sources management - Phase 6: Background sync with configurable intervals and push notifications - Phase 7: Complete rule editor and polished UI components Supported data types: - Steps, Heart Rate, Blood Pressure, SpO2, Sleep - Distance, Floors Climbed, Active Energy, HRV, Respiratory Rate Architecture: SourceManager -> DataReader -> RuleEngine -> MergeEngine -> DataWriter
