+/**
+ * Fixes npm workspace hoisting for React Native native modules.
+ *
+ * npm workspaces hoists all deps to the root node_modules by default.
+ * Native modules like @react-native-firebase/* and @shopify/react-native-skia
+ * break when hoisted because:
+ *   - Firebase podspecs use relative paths to sibling packages (../app/package.json)
+ *   - Skia native bindings must resolve from the app's node_modules
+ *
+ * This script moves hoisted native packages back into apps/mobile/node_modules
+ * so CocoaPods autolinking and Metro resolve them correctly.
