//! Terminal User Interface for watch mode.
//!
//! This module provides a rich TUI for monitoring lint results in real-time.
//! It uses ratatui for rendering and crossterm for terminal manipulation.
//!
//! ## Features
//!
//! - **File tree**: Shows watched files with status indicators
//! - **Issue list**: Scrollable list of lint issues
//! - **Status bar**: Current status, counts, and keyboard shortcuts
//! - **Help overlay**: Quick reference for keyboard shortcuts
//!
//! ## Keyboard Shortcuts
//!
//! - `q` / `Ctrl+C` - Quit
//! - `↑/↓` or `j/k` - Navigate issues
//! - `Enter` - Open file in editor
//! - `Tab` - Switch focus between panels
//! - `r` - Force re-run all
//! - `c` - Clear results
//! - `?` - Toggle help overlay
