Implement "Terminal Warrior" (TUI) Mode #3
Description
The README architecture claims support for a "Terminal UI" via cli-chat-rs. However, the current code in main.rs contains only a placeholder:
// Launch TUI mode (Placeholder for cli-chat-rs integration)
println!("Starting TUI mode... (Not implemented yet, exiting)");
process::exit(0);
Action: Integrate the cli-chat-rs library into main.rs. When "Terminal" is selected, it should initialize the TUI loop instead of exiting.
