FIXME: Vendored AFNetworking AFURLRequestSerialization referenced upstream PR #172

Location: Example_Objc/Vendor/AFNetworking/AFURLRequestSerialization.m

Found comment: "// FIXME: AFNetworking/AFNetworking#3028"

Issue: A vendored copy of AFNetworking contains a FIXME pointing to an upstream PR. Recommended actions:

• Check if the upstream PR has been merged; if so, update the vendored code or switch to the latest upstream release.
• If not merged, consider removing the vendored copy and add AFNetworking as a dependency via CocoaPods/Carthage, or apply a minimal patch and document it.

Filing this issue to track dependency cleanup and reduce maintenance burden.
