Implement promiseAllSettled(promises) function that works like native Promise.allSettled().

Requirements:

• Takes an array of promises
• Returns a promise with an array of all promise results
• NEVER rejects - always resolves
• Each result is an object with { status, value/reason }
• status: "fulfilled" or "rejected"
• fulfilled: { status: "fulfilled", value: result }
• rejected: { status: "rejected", reason: error }
• Empty array returns []
• DO NOT use built-in Promise.allSettled()

Example:

const results = await promiseAllSettled([
  Promise.resolve(1),
  Promise.reject('error'),
  Promise.resolve(3)
]);
// results = [
//   { status: 'fulfilled', value: 1 },
//   { status: 'rejected', reason: 'error' },
//   { status: 'fulfilled', value: 3 }
// ]
