ci: restore Xcode 26.0 upgrade to release pipeline (#67)

* ci: restore Xcode 26.0 upgrade to release pipeline

Restore the Xcode 26.0 and macOS 26 runner upgrade from PR #62 that was
lost when we reverted the pipeline to Oct 10 version in PR #65.

Changes:
- runs-on: macos-latest → macos-26
- Xcode_16.0 → Xcode_26.0
- Fastlane 2.226.0 → 2.228.0

This brings the release.yml workflow back in sync with the other workflows
(ios-build-test.yml, code-quality.yml, dependency-update.yml) which all
already use Xcode 26.0 and macOS 26 runners.

Benefits from PR #62:
- Latest iOS 26 SDK support
- AI-powered development tools
- Up to 16x faster list updates in SwiftUI
- Improved compilation caching
- Enhanced Swift 6 support
