// Local scan of an iOS project for Apple's privacy manifest rules (no network, no credentials, no config needed).
// storebound privacy-manifest --ios ios/App [--sdk-dirs node_modules/@capacitor,node_modules/some-plugin] [--json]
// Reports: the app's PrivacyInfo.xcprivacy, required-reason API categories used in app sources vs declared, tracking
// flag vs the ATT usage string, and every SDK (CocoaPods, .xcframework / .framework, SwiftPM checkouts, local SwiftPM
// packages, the native plugins of a Capacitor / Cordova / React Native app found through node_modules and workspaces
// the way Node resolves them, so a monorepo's apps/native/node_modules works without flags, and --sdk-dirs)
// without its own manifest. Heuristic text scan: it can miss uses inside binaries and flag harmless matches.
