feat(tui): introduce comprehensive state management for TUI interface

- Add AppStateRest as the central state struct for managing TUI state. - Implement InputState for handling user input, autocomplete, and history. - Create MiscState to manage overlays, notifications, and editor state. - Introduce ScrollState for viewport scrolling functionality. - Develop TranscriptCache for efficient message rendering in the chat pane. - Implement SimpleAgent and SimpleWorkflowEngine for agent lifecycle management. - Add helper functions for managing effort levels and token counting. - Organize state-related modules for better maintainability and clarity.

+//! Progress reporting types for long-running agent and subagent operations.

+//! spinner, progress bar, and agent-status sidebar. They are pure domain
+//! types with no I/O or framework dependency.
