Issue #90: Duo submissions are open, a February certificate deadline, and #if for deployment targets

Xcode 27.1 RC shipped and App Store Connect now accepts iPhone Duo builds, with review needing to clear by October 23. New App Store Connect tools went live the same day: product page headers, search result assets, a preview tool, and an Asset Library for pre-approving creative. Mac developers face a hard deadline: the original Developer ID Certification Authority expires February 1, 2027, breaking unsigned .pkg installers unless re-signed with G2 certificates (choosing the G2 Sub-CA specifically). Apple also announced upcoming stricter Full Disk Access controls with no technical details yet. SE-0554, a Swift Evolution proposal for compile-time deployment-target checks (useful for package authors adopting new types), is in review through October 12. Other items cover Xcode MCP's Preview tool returning stale renders, AsyncSequence-based incremental screen loading, and SwiftUI's new lineHeight modifier and inline title centering quirks.
