🎨 Palette: Enhance CLI UX with colors and inclusive high score tracking

[aidasofialily-cmd]

I've implemented several micro-UX improvements to the SPEED CLICKER game to make it more delightful and inclusive:

1. Visual Delight: The pre-game countdown and "GO!" prompt are now colorized (Bold Yellow and Bold Green), providing a much more engaging transition into the game.
2. Immediate Feedback: During gameplay, players now see their current high score live (Score: X | High: Y). This provides immediate context for their progress.
3. Inclusivity for New Players: I fixed a logic bug where the "NEW BEST! 🥳" message and final congratulations would only show if the player already had a recorded high score. Now, every player's first successful game is celebrated.
4. UI Polish: Colorized the achievement messages to make them stand out.
5. UX Journal: Added a new entry to the Palette journal reflecting on the importance of inclusive achievement feedback for first-time players.

Tested via make, verify_ux.py, and manual terminal output inspection using a pseudo-terminal.
