Bump iOS/Xcode Version

This skill guides you through bumping the iOS and Xcode version in Eigen.

Before You Start

Prompt the user for the target version:

• Ask which iOS version they want to bump to (e.g., "26.2")
• Ask which Xcode version they want to use (e.g., "26.2")
• Ask which iPhone model to use for simulators (e.g., "iPhone 17 Pro")

Verify version support before making changes:
