Fix TUI cancel busy animations

[Hmbown]

Summary

• clear local busy turn state, retry banner, and runtime turn id when Esc/Ctrl+C cancels a turn
• stop terminal title/taskbar busy animations for cancelled, failed, and completed turns
• keep Esc routed to cancel when runtime status is still in_progress after a loading-state race
