Not necessary, as the code in this PR was tested in included PRs (listed above). Otherwise:

1. Run the app, smoke test main features
2. Focus if experiments and features which depend on feature flags work as expected.

Regression Notes

1. Potential unintended areas of impact

   • Code related to experiments, feature flags and features in development

2. What I did to test those areas of impact (or what existing automated tests I relied on)

   • The code generated by old annotation processor is the same as the one generated by the new processor

3. What automated tests I added (or what prevented me from doing so)

   • Migrate :libs:processors to ksp #20217 is carefully tested by automatic tests (some of them are also integration, not only unit)

Thank you for your work on this @wzieba 🏅
The code changes look consistent and I didn't notice any change while sanity testing the app on a Pixel 8 (Android 14) 🎉
