[glaeesas]

This PR adds a GitHub Actions workflow that automatically updates the _0xData array in JS/main.js whenever you add or change games in your Games folder.

Features:

• Finds the main HTML file (prefers index.html)

• Sets description to "Coming soon. Edit this description in main.js."
• Generates clean IDs from folder names

How to use:

1. Just drop a new game folder with an index.html into Games/
2. Push to main
3. The workflow runs and creates a PR with the updated registry

After merging, just find the game entry in _0xData and change the desc field.
