Add Lights Out Puzzle Game

Description:
I want to add a new game to the collection — Lights Out, a classic puzzle where clicking a tile toggles it and its adjacent tiles. The objective is to turn off all the lights on the grid.

Gameplay Overview:
- Grid size: 5x5
- Each tile can be either on (lit) or off
- Clicking a tile toggles: That tile & Its top, bottom, left, and right neighbors
- The player wins when all lights are turned off

Benefits:
- Puzzle-based, visually interactive, and fits well in the collection of logic games
- Lightweight and fun
