[Android] Fix CMake build on React Native 0.81: use jsctooling instead of jscexecutor

Description

### Environment
- **react-native-worklets**: 0.5.1
- **React Native**: 0.81.x (Expo SDK 54)
- **Platform**: Android

### Problem
On Android with React Native 0.81, the CMake build fails with:

CMake Error at CMakeLists.txt:59 (add_library):
Target "worklets" links to target "ReactAndroid::jscexecutor" but the
target was not found. Perhaps a find_package() call is missing for an
IMPORTED target, or an ALIAS target is missing?

In RN 0.81 the prefab no longer exposes `ReactAndroid::jscexecutor`; the correct target is `ReactAndroid::jsctooling`.

### Suggested fix
In `android/CMakeLists.txt`, for the JSC branch, use `jsctooling` for RN 0.81+ and keep `jscexecutor` for 0.76–0.80:

```cmake
elseif(${JS_RUNTIME} STREQUAL "jsc")
  if(ReactAndroid_VERSION_MINOR GREATER_EQUAL 81)
    # RN 0.81+ uses jsctooling (jscexecutor target removed in prefab)
    target_link_libraries(worklets ReactAndroid::jsctooling)
  elseif(ReactAndroid_VERSION_MINOR GREATER_EQUAL 76)
    target_link_libraries(worklets ReactAndroid::jscexecutor)
  else()
    target_link_libraries(worklets ReactAndroid::jscexecutor)
  endif()

Patch file

We use this as a patch-package patch; the generated patch is in patches/react-native-worklets+0.5.1.patch (it also includes minor formatting/whitespace changes). The important part is the JSC branch above.

Happy to open a PR if you prefer.

### Steps to reproduce

1. Créer un projet Expo SDK 54 (React Native 0.81) ou utiliser un projet existant avec ces versions.
2. Installer `react-native-reanimated` (qui tire `react-native-worklets@0.5.1`) et configurer le plugin Babel si besoin.
3. Lancer un build Android (EAS Build ou `expo run:android` / `./gradlew assembleRelease`).
4. La phase CMake de `react-native-worklets` échoue avec l’erreur : `Target "worklets" links to target "ReactAndroid::jscexecutor" but the target was not found`.

**En résumé** : avec React Native 0.81 + JSC, le build Android échoue car le prefab n’expose plus la cible `ReactAndroid::jscexecutor`, utilisée par `react-native-worklets` pour RN >= 76.

Start in android/CMakeLists.txt and inspect the JSC branch and ReactAndroid version handling. Reproduce with React Native 0.81.5 and JSC using an Android Gradle or CMake build; done means RN 0.81 builds without the missing jscexecutor target while RN 0.76–0.80 remains supported.
