Sweep: Implement a greedy snake

[sweep-ai[bot]]

Description

This pull request introduces a complete implementation of the classic Snake game, replacing the initial placeholder content in index.html with a fully interactive game. The game features a snake that players can control to eat apples, increasing the snake's length and the player's score with each apple. The game ends when the snake collides with itself or the wall.

Summary

• Changed the <title> in index.html from "Hello World" to "Snake Game".
• Added inline <style> for the game canvas in index.html to ensure the game area is properly bordered.
• Replaced the placeholder content in index.html body with a <canvas> element for the game and a <div> to display the score.
• Included a new JavaScript file snake.js to contain the game logic.
• Implemented game initialization, rendering, and update logic in snake.js, including:
  • Game state management (snake position, direction, apple position, score).
  • Collision detection for game over conditions.
  • Keyboard event handling for snake direction control.
  • Dynamic apple placement upon being "eaten" by the snake.
  • Score tracking and display update.
• Utilized HTML5 Canvas API for game rendering.

Fixes #7.
