Add GET /hello endpoint

[Claude]

Implements a /hello endpoint that responds with "Hello!" text.

Changes

• Added GET /hello route in index.js between root handler and middleware setup
• Follows existing request logging pattern (timestamp, method, path)

app.get("/hello", (req, res) => {
  console.log(`${new Date()} ${req.method} ${req.path}`);
  res.send("Hello!");
});

Original prompt
