⚡ Feature Request: Add "Shrink" Power-Up

Description:

Introduce a new power-up called “Shrink” that reduces the snake’s length by 3 segments immediately after collecting it. This mechanic helps players escape tight spaces or strategically reset their snake’s size.

---

🎯 Requirements:

• Add a new item (e.g., a minus icon or shrinking fruit) that spawns randomly like other power-ups.
• When collected, the snake’s length should be reduced by 3 segments instantly.
• If the snake has fewer than 4 segments, it should shrink to a minimum of 1 segment — it should never disappear completely.
• Optional: Add a short visual cue (flash, shrink animation, or color change) to indicate the effect.

---

💡 Implementation Hints:

• The snake’s body is typically stored as an array of segments.
• Use snake.splice() or a similar method to remove the last 3 segments upon power-up collection.
• Use a distinct itemType or flag to handle the shrink effect within your collision or power-up logic.

---

🧩 Files Likely Involved:

• script.js (or the main game logic file managing snake state)
• Assets or functions related to power-up spawning and handling

---

✅ Acceptance Criteria:

• Power-up item appears randomly on the game board.
• Snake length reduces by exactly 3 segments upon pickup.
• Minimum snake size is enforced (cannot drop below 1 segment).
• No bugs or crashes occur when shrink triggers during movement or power-up stacking.

---

🧪 Optional Bonus:

• Display an on-screen indicator or play a short sound when the Shrink power-up is triggered.
• Track how many times the player has used the Shrink ability for potential future stats or achievements.
