What

Adds a caret-* color utility so caret-black, caret-red-500, etc. set the cursorColor prop on TextInput again.

Closes #1756

Why

In v4, Nativewind mapped caret-* to the cursorColor prop. v5 dropped that mapping and it was not listed in the migration guide as an intentional removal, so the utilities silently stopped working.

How

@utility caret-* {
  caret-color: --value(--color-*);
}

react-native-css already maps the standard CSS caret-color property to the cursorColor prop (see the default mapping in parsePropAtRule, compiler/atRules.js), so emitting caret-color restores the v4 behavior cleanly. I placed it next to the existing tint-* utility to keep the RN-specific color utilities together.

A note on approach: the issue suggested wiring this up with @prop. I tried the form that mirrors tint-* (-rn-cursor: --value(--color-*); @prop -rn-cursor cursorColor;), but because caret-color -> cursorColor is already a built-in mapping, the custom -rn-cursor declaration also leaked through as a cursor entry in style, producing a duplicate value. Using the standard caret-color property goes through the same mapping mechanism without the leak. Happy to switch to an explicit @prop mapping if you prefer that style.

Test

Added src/__tests__/caret.tsx, following the existing test conventions:

test("caret-black", async () => {
  expect(await renderCurrentTest()).toStrictEqual({
    props: {
      cursorColor: "#000",
      style: {},
    },
  });
});

Full suite is green locally (yarn jest: 8 suites, 36 tests passing). yarn typecheck passes.
