nativeStyleMapping crashes when value is boolean (path.split is not a function)

[clancywist]

Bug

nativeStyleMapping() in dist/module/native/styles/index.js crashes when a nativeStyleMapping config entry has a boolean value (true) instead of a string path.

Reproduction

Use text-center (or any class that produces textAlign) on a <TextInput>:

<TextInput className="text-center text-2xl text-white" />

Error:

TypeError: path.split is not a function (it is undefined)
  at index.js:329

Root cause

TextInput.js declares:

const mapping = {
  className: {
    target: "style",
    nativeStyleMapping: {
      textAlign: true  // <-- boolean, not a string
    }
  }
};

At line 322-329 of dist/module/native/styles/index.js:

for (const [key, path] of Object.entries(config.nativeStyleMapping)) {
  // ...
  const tokens = path.split(".");  // path is `true`, not a string → crash
}

Object.entries({ textAlign: true }) yields ["textAlign", true]. Then true.split(".") throws.

The same pattern exists in ActivityIndicator (color: true), ImageBackground (backgroundColor: true), and Button (color: true).

Suggested fix

const resolvedPath = typeof path === "string" ? path : key;
const tokens = resolvedPath.split(".");

When path is true, fall back to key as the prop name (same-name mapping).

Environment

• react-native-css: 3.0.4
• nativewind: 5.x
• Expo SDK: 55
• Platform: iOS (Expo Go simulator)
