fix: resolve Windows circular dependency and macOS platform compatibility

Windows fixes:
- Use windows-2022 runner (SDK 10.0.22621) instead of windows-latest (SDK 10.0.26100.0)
- Revert to Swift 6.0 for LoopAlgorithm compatibility
- Avoids "cyclic dependency in module ucrt: ucrt -> _Builtin_intrinsics -> ucrt" error

macOS fixes:
- Add explicit platform requirements to Package.swift
- Set minimum macOS 13.0 to match LoopAlgorithm dependency requirements
- Resolves "library requires macos 10.13 but depends on product which requires macos 13.0"

Based on research from Swift issues #79745 and #58450 showing SDK compatibility problems.
