Feature request: publish Android wheels for Traits

Would you consider adding official Android wheels for Traits?

Android is now an officially supported CPython platform, and the Python packaging ecosystem has recently gained support for standard Android wheel tags and Android builds through cibuildwheel.

Traits is currently one of the remaining packages in my Android Python application that needs to be cross-compiled locally with `python-for-android`. The application uses Traits itself, but not TraitsUI.

`python-for-android` now has support for consuming compatible prebuilt Android wheels, so publishing Traits wheels for Android would remove the need for a dedicated Traits build recipe.

A typical target of interest would be:

```
CPython 3.13+
Android API 24+
arm64-v8a
```

Traits already uses `cibuildwheel` for binary wheel generation on the supported desktop platforms, so I was wondering whether extending the existing wheel build workflow to Android would now be feasible.

I would also be happy to test experimental Android wheels in a real Kivy / traits/python-for-android application if that would be useful.

Start by inspecting Traits' existing cibuildwheel workflow for desktop binary wheels and checking how Android wheel targets are configured. Verify whether the proposed CPython 3.13+, Android API 24+, arm64-v8a target can be built and consumed by python-for-android. Done means the workflow publishes compatible official Android wheels and they work in a real Kivy/Traits application.
