Pull request overview

This pull request raises the minimum supported macOS version from 12.0 (Monterey) to 13.0 (Ventura) across the entire codebase. This change enables removal of version availability checks and fallback code that was previously needed to support macOS 12 and earlier versions. The update simplifies the codebase by eliminating conditional compilation for older APIs.

Changes:

• Updated minimum macOS version to 13.0 in all build configuration files (Package.swift, CMakeLists.txt, xcconfig, plist)
• Removed @available(macOS 13.0, *) and if #available(macOS 13.0, *) version checks throughout Swift and Objective-C++ code
• Consolidated Xcode project build settings by removing duplicate MACOSX_DEPLOYMENT_TARGET declarations
