Random exit in cli mode

[FlatMapIO]

Seems to be the problem of createCDNLoader function

 function fetchCollection(name: string) {
    if (!supportedCollection.includes(name))
      return undefined
    if (!cache.has(name))
      cache.set(name, $fetch(`${cdnBase}@iconify-json/${name}/icons.json`))
    return cache.get(name)!
  }

I'm not sure how $fetch is implemented, but i've tested the fetch in node and it probably doesn't work.

await fetch("https://esm.sh/@iconify-json/carbon/icons.json")

There is no problem running unocss with bun and testing the fetch function above

It seems to be a node problem, bun and deno are working fine. nodejs/node#45419

I propose to raise $fetch to the try block to let the process know what happened when it exits
