refactor(post): consolidate post sync to PostSyncService and remove ProcessPostUseCase
- Replace ProcessPostUseCase with new PostSyncService in src/services/post/ - Add postListStore for state management in src/stores/post/ - Remove deprecated ProcessPostUseCase and ProcessMessageUseCase files - Delete architecture documentation files (ARCHITECTURE_REFACTOR_PLAN.md, architecture-comparison-report.md) - Update all consumers (HomeScreen, PostDetailScreen, SearchScreen, useUserProfile, useDifferentialPosts) - Simplify postService to only contain API layer methods - Remove unused type exports from message stores BREAKING CHANGE: ProcessPostUseCase and ProcessMessageUseCase have been removed. Use postSyncService for post operations instead.
