🎨 Palette: Add CLI Arguments and Accessibility Options

[EiJackGH]

• 💡 What: Implemented argparse to allow CLI configuration of simulation parameters, and added --quiet and --no-color flags.
• 🎯 Why: Users need control over simulation length and verbosity. Colors are nice but can be inaccessible or unwanted.
• 📸 Before/After: N/A (CLI behavior change)
• ♿ Accessibility: Added --no-color flag for users who cannot distinguish colors or prefer plain text logs.
• Tests: Added test_simulation.py with unit tests for core logic. Verified CLI flags manually.
