Tests

Use test selection for optimized CI runs

Reduce wait time and cloud cost up to 20x by adopting predictive test selection:

1. Only run needed tests in a PR.
2. After merging to main, run many (or all) tests to gain full confidence.
3. If all passed, start deployment.
4. Else, on any failure, revert the relevant commit(s).

So, let’s get started.
