Previous keyboard event polling didn't work for Ctrl+C in raw mode.
Now using tokio::signal::ctrl_c() with a background task that signals
the render loop through a channel when Ctrl+C is pressed.
Changes:
- Added "signal" and "sync" features to tokio dependency
- Spawn background task to listen for Ctrl+C signal
- Use mpsc channel to communicate signal to render loop
- Keep 'q' and ESC keyboard shortcuts for convenience
Ctrl+C now properly exits looping animations.
