Note

Low Risk
Low risk: only updates the iOS Helium CocoaPods dependency version and bumps the package patch version; no code or behavior changes in this repo beyond dependency resolution.

Overview
Updates the iOS podspec to depend on Helium 4.4.8 (from 4.3.0).

Bumps package.json version from 3.0.23 to 3.0.24 to publish the dependency update.
