Context-Aware Disc Swap Menu

📋Summary

Only display the “Swap Discs” option in the pause menu when a game has multiple discs.

❗Problem

Currently, the “Swap Discs” option appears for all games when the swap script is enabled—even single-disc titles. This adds unnecessary clutter and confusion.

💡Proposal

Automatically hide the “Swap Discs” option unless the selected game is recognized as a multi-disc title.

✅Benefits

• Cleaner pause menu

• Avoids user confusion

• Aligns with existing metadata detection for disc counts
