+/// Manages all application state including authentication, chats, messages,
+/// and UI state. Integrates with TDLib через `TdClient` and handles user input.
+///
+/// # State Machine
+///
+/// The app uses a type-safe state machine (`ChatState`) for chat-related operations:
+/// - `Normal` - default state
+/// - `MessageSelection` - selecting a message
+/// - `Editing` - editing a message
+/// - `Reply` - replying to a message
+/// - `Forward` - forwarding a message
+/// - `DeleteConfirmation` - confirming deletion
+/// - `ReactionPicker` - choosing a reaction
+/// - `Profile` - viewing profile
+/// - `SearchInChat` - searching within chat
+/// - `PinnedMessages` - viewing pinned messages
+///
+/// # Examples
+///
+/// ```no_run
+/// use tele_tui::app::App;
+/// use tele_tui::app::methods::navigation::NavigationMethods;
+/// use tele_tui::config::Config;
+///
+/// let config = Config::default();
+/// let mut app = App::new(config, std::path::PathBuf::from("tdlib_data"));
+///
+/// // Navigate through chats
+/// app.next_chat();
+/// app.previous_chat();
+///
+/// // Open a chat
+/// app.select_current_chat();
