🧪 Nala E2E Tests

Nala tests run automatically when you open this PR.

To run Nala tests again:

1. Add the run nala label to this PR (in the right sidebar)
2. Tests will run automatically on the current commit
3. Any future commits will also trigger tests as long as the label remains

To stop automatic Nala tests:

• Remove the run nala label

Note: Tests only run on commits if the run nala label is present. Add the label whenever you need tests to run on new changes.
