detectSpmStatus function

SpmStatus detectSpmStatus(String baseDir)

Detects SPM and CocoaPods status for a plugin directory.

Handles both the flat layout (ios/Package.swift) and the Flutter 3.41+ nested layout (ios/<pluginName>/Package.swift).

  final macosPodspecs = macosDir.existsSync() ? macosDir.listSync().whereType<File>().where((f) => f.path.endsWith('.podspec')).toList() : <File>[];
