Integrate `expo-callkit-telecom` to support native system call handling (answering, ending, and muting via system UI). This includes a new `callKeepService` and a `CallKeepBootstrap` component to manage the lifecycle of system call events.
Additionally, improves the calling experience by:
- Adding support for group calls with participant tracking and UI indicators.
- Enhancing LiveKit integration by replacing polling with event-driven video track synchronization.
- Updating `WebSocketService` to prevent disconnection when the app enters the background during an active call.
- Adding new WebSocket message types for participant join/leave events and group invites.
- Refining call UI components (`CallScreen`, `FloatingCallWindow`, `IncomingCallModal`) for better visual feedback and safe area handling.
Refactor LiveKit service to use event-driven updates for local and remote tracks, improving performance and reliability.
Looking at the changes:
1. **New files**:
- `app/(app)/(tabs)/profile/account-deletion.tsx` - account deletion screen
- `app/(app)/(tabs)/profile/privacy-settings.tsx` - privacy settings screen
- `src/screens/profile/AccountDeletionScreen.tsx` - account deletion implementation
- `src/screens/profile/PrivacySettingsScreen.tsx` - privacy settings implementation
2. **Modified files**:
- Database changes: `LocalDataSource.ts`, `DatabaseManager.ts`, `DatabaseConfig.ts`, `MigrationManager.ts` - refactoring database layer (removing LockManager, simplified initialization, added retry logic)
- Auth store: `authStore.ts` - changed `initDatabase` to `switchDatabase`
- Auth service: `authService.ts` - added privacy settings and account deletion methods
- DTOs: `dto.ts` - added PrivacySettingsDTO, DeletionStatusDTO, VoteOptionDTO, VoteResultDTO types
- Navigation: `hrefs.ts` - added new href functions for privacy settings and account deletion
- Profile screens: `SettingsScreen.tsx`, `index.ts`, `_layout.tsx` - added new menu items and routes
- Various message screens - added keyboard handling props
- `app/_layout.tsx` - added CSS for mobile touch handling
- `CreatePostScreen.tsx` - fixed vote_options format
- `PostDetailScreen.tsx` - added type annotations for vote handling
- `MediaCacheManager.ts` - updated to use new expo-file-system API
- `VerificationSettingsScreen.tsx` - fixed type safety
- `AccountSecurityScreen.tsx` - styling refactoring
This is a multi-faceted change involving:
Database refactoring, new privacy/account deletion features, bug fixes, and UI improvements. The database changes appear to be refactoring without new functionality. The most significant changes are the privacy settings and account deletion features, plus bug fixes like the vote options format and mobile touch handling.

feat(profile): add privacy settings and account deletion screens
Add privacy settings and account deletion functionality with new screens and APIs. Refactor database initialization to use switchDatabase for user switching. Fix vote options format in post creation and add type safety to vote handling. Improve mobile touch handling in layout and message screens. Update media cache to use new expo-file-system API.
BREAKING CHANGE: Database initialization now uses switchDatabase instead of initDatabase for user switching
- Remove legacy database.ts, LocalDataSource.ts, and MessageRepository.ts
- Create new src/database/ module with messageRepository, userCacheRepository, conversationRepository, and groupCacheRepository
- Update all consumers to import from @/database instead of services/database
- Add web platform blur handling for modal components to fix focus issues
- Flatten SystemMessageItem and NotificationsScreen styles for consistent design
- Add draggable slider in ChatSettingsScreen and dynamic font size support
- Introduce 9 new chat color themes
- Add profile screens for about, terms, and privacy policy with navigation routes
- Add policy links to login and registration screens
- Fix post share URL format from /posts/ to /post/
Refactor LocalDataSource to reuse the shared database connection from database.ts, avoiding OPFS file handle conflicts. Add retry logic with exponential backoff for database open operations, particularly important for Web/OPFS environments. Also add dynamic theme support to chat input and message bubble styles, using theme colors instead of hardcoded values for better light/dark mode support.
BREAKING CHANGE: Database initialization now requires userId to be passed explicitly for user-specific databases
- Replaced SSEClient with WSClient for handling real-time messaging.
- Updated ProcessMessageUseCase to initialize WebSocket listeners.
- Refactored messageService to prioritize WebSocket for sending messages, with fallback to HTTP.
- Removed sseService and adjusted imports across the application to utilize wsService.
- Enhanced message handling and connection management for improved performance and reliability.
- Introduced a promise-based initialization mechanism in LocalDataSource to prevent concurrent initialization issues.
- Updated PostRepository to utilize an enqueueWrite method for database operations, ensuring thread-safe writes.
- Refactored ChatScreen to improve message loading logic, including preloading history and managing scroll behavior more effectively.
- Enhanced message rendering logic to maintain correct indices in inverted lists and optimize user experience during scrolling.
Migrate post-related operations from direct service/store calls to a new use case architecture featuring differential updates. Key changes include: (1) introduce ProcessPostUseCase to handle like, unlike, favorite, unfavorite, delete, and fetch operations with proper state management, (2) add useDifferentialPosts hook for efficient list rendering with minimal re-renders, (3) add PostDiffCalculator and PostUpdateBatcher in infrastructure layer for incremental updates, (4) deprecate NotificationItem component in favor of SystemMessageItem, (5) remove deprecated interactive methods from userStore, (6) add posts_cache table to local datasource, (7) clean up legacy MessageDTO and ConversationDTO types, (8) remove deprecated hook useBreakpointCheck, (9) refactor MessageBubble to use measureInWindow directly for better React Native compatibility
Replace WebSocket-based real-time communication with Server-Sent Events (SSE) across the messaging infrastructure. This includes:
- Create new SSEClient datasource to manage SSE connections
- Create new SSEMessageHandler to process SSE events
- Update ProcessMessageUseCase to use SSEClient instead of WebSocketClient
- Update MessageManager and MessageStateManager to work with SSE handlers
- Rename connection state variables from `isWebSocketConnected` to `isSSEConnected`
- Update type definitions in dto.ts (WSEventType → SSEEventType, etc.)
- Delete obsolete WebSocketClient and WebSocketMessageHandler files
- Update comments and documentation to reflect SSE terminology
This refactoring aligns with the backend's SSE implementation for better compatibility with React Native's networking capabilities.
