🎨 Palette: Enhance personal best achievement styling in CLI HUD

[aidasofialily-cmd]

🎨 Palette Micro-UX Enhancement

💡 What

• Added bold yellow (CLR_CTRL) highlighting and celebratory emojis (✨🥳) to the real-time "NEW BEST!" high-score notification in the live HUD and game-over summary.
• Guaranteed that an ANSI color reset sequence (CLR_RESET) is output at the end of every carriage-returned HUD line update to prevent active mode formatting from leaking into terminal text.

🎯 Why

• Elevates the celebratory feel and visual prominence of personal best records during gameplay.
• Prevents subtle ANSI formatting leakage bugs in terminal sessions when mode or score indicators change.

♿ Usability / Accessibility

• Enhances visual contrast and distinction for game achievements in CLI/terminal environments.
• Maintained clean ANSI terminal sequence resets on all exit paths and output lines.
