Promise Delay

Create a function that resolves with a value after a delay.

Requirements:

• Implement delay that takes a value and milliseconds
• Return a Promise that resolves with the value after the delay
• Support chaining with other promises
• Handle zero and negative delays (resolve immediately)

Example:

delay('Hello', 1000).then(value => {
  console.log(value); // 'Hello' (after 1 second)
});

// Chaining
Promise.resolve(5)
  .then(n => delay(n * 2, 500))
  .then(result => console.log(result)); // 10 (after 500ms)
