🎨 Palette: Add interactive CLI progress bar for quiet mode

[EiJackGH]

💡 What: Added a dynamic, in-place text progress bar that animates using carriage returns when running the simulation in --quiet mode.
🎯 Why: Long-running simulations without logging make the application feel hung, which can cause user anxiety. The progress bar provides visibility without polluting standard output, making the CLI app much more pleasant to use.
📸 Before/After: Before, --quiet was completely silent until the end. After, it shows a dynamic progress bar if running in an interactive terminal.
♿ Accessibility: The bar is conditional on sys.stdout.isatty() so it won't break screen readers or automated CI/CD logs.
