What is happening?

macOS 15 introduced Local Network Privacy support in macOS 15. This will prompt the user when you request access to devices on the local network (such as through mDNS).

However, there is no user in CI to give permission so it will hang and then on the next run it will fail

Flutter usually gets the Dart VM url from the device logs, which we get from either ios-deploy or idevicesyslog, depending on the iOS version. However, both of those tools are flakey so we use mDNS as a fallback for discovering the Dart VM url. We also have been considering using mDNS as the primary discovery method so we can reduce usage of iproxy by targeting the device IP (found via mDNS) directly.

Since there is no user in CI, we need to figure out how to give this permission.
