🎨 Palette: Enhanced Score Readability and Achievement Context

[aidasofialily-cmd]

💡 What: This PR enhances the "Speed Clicker" terminal interface by adding thousands separators to all score displays, improving HUD styling consistency, and providing better context for achievements.

🎯 Why: In a fast-paced clicking game, large numeric values (e.g., 10000) become difficult to parse quickly. Adding separators and consistent color-coding improves readability. Providing the previous high score on the game-over screen gives users a better sense of progress and achievement.

♿ Accessibility:

• Improved visual hierarchy using bold color-coding for labels vs values.
• Enhanced readability of large numbers through standard formatting.
• Used CLR_EOL (\033[K) for cleaner terminal updates, reducing visual artifacts during rapid score changes.

🎨 Changes:

• Implemented formatWithCommas utility in src/main.cpp.
• Updated Intro, Live HUD, and Game-Over screens to use formatted numbers.
• Styled HUD labels with CLR_SCORE (Bold Cyan) and "NEW BEST!" with CLR_NORM (Bold Green).
• Added previous personal best to the "New personal best" congratulation message.
