Step 1 - Build and app wiring

• Added Android project plugin configuration for Hilt and Kotlin serialization.
• Added dependency repositories and explicit app module include in settings.
• Added app dependencies for Retrofit/OkHttp, DataStore, coroutines, Hilt, and unit testing.
• Enabled INTERNET permission and registered MessengerApplication in manifest.
• Added MessengerApplication with HiltAndroidApp.

Step 2 - Network/data core + DI

• Fixed DTO/Auth API serialization annotations and endpoint declarations for /api/v1/auth/login, /api/v1/auth/refresh, /api/v1/auth/me.
• Implemented DataStore-based token persistence with a corrected getTokens() read path.
• Added auth network stack: bearer interceptor, 401 authenticator with refresh flow and retry guard.
• Added clean-layer contracts and implementations: domain/common, domain/auth, data/auth/repository.
• Wired dependencies with Hilt modules for DataStore, OkHttp/Retrofit, and repository bindings.

Step 3 - Minimal auth UI and navigation

• Replaced Phase 0 placeholder UI with Compose auth flow (AuthViewModel + login screen).
• Added loading/error states for login and startup session restore.
• Added navigation graph: AuthGraph (login) to placeholder Chats screen after successful auth.
• Implemented automatic session restore on app start using stored tokens.

Step 4 - Unit tests

• Added DataStoreTokenRepositoryTest for token save/read and clear behavior.
• Added NetworkAuthRepositoryTest for login success path and 401 -> InvalidCredentials error mapping.

Step 5 - Chat Room models and persistence core

• Added domain chat model (ChatItem) for chat list rendering concerns.
• Added Room entities: chats, users_short with sort-friendly indices.
• Added ChatDao with observeChats(), upsertChats(), and transactional clearAndReplaceChats().
• Added MessengerDatabase and Hilt database wiring (DatabaseModule).

Step 6 - Chat API and repository sync

• Added chat REST API client for /api/v1/chats and /api/v1/chats/{chat_id}.
• Added chat DTOs and remote/local mappers (ChatReadDto -> ChatEntity/UserShortEntity -> ChatItem).
• Implemented NetworkChatRepository with cache-first flow strategy (Room first, then server sync).
• Added chat domain contracts/use-cases (ChatRepository, observe/refresh use-cases).
• Wired chat API/repository via Hilt modules.
