Add Image Hunt Game

This PR adds the Image Hunt game, built with React, TypeScript, and Next.js, integrated with the Gno blockchain.

Key Features:

• Players guess a target image from a 30-image grid based on clues (brightness, color, and direction).
• Scores are saved on-chain and displayed in a leaderboard.
• Adena wallet integration for blockchain interactions.
• Leaderboard sorted by top scores, fetched from the Gno chain.

Environment variables and wallet setup are required to run the game.

You can find the game repo here: ImageHuntGno
