🎨 Palette: CLI Game UX Enhancements

[aidasofialily-cmd]

💡 What: This PR enhances the SPEED CLICKER CLI game with small touches of delight and improved feedback.

• Visual Engagement: The countdown digits are now Bold Yellow, and the "GO!" prompt is Bold Green, making the start of the game more distinct and exciting.
• Real-time Reward: A live "High: [score]" indicator was added to the HUD, updating immediately as the player sets a new record. This provides immediate tactile feedback and a sense of progression.
• Inclusivity: The "NEW BEST!" and final congratulations logic was updated to celebrate first-time players. Previously, these only triggered if a prior high score existed; now, every player's first successful run is celebrated.

🎯 Why: These micro-UX improvements make the game feel more polished, responsive, and rewarding, especially for new users.

♿ Accessibility: Improved visual hierarchy and feedback through standardized ANSI color sequences. All terminal state management (cursor hiding/restoration) was preserved and verified.
