When the "go back" button is clicked, the user is sent back to the `main` function graph. The breadcrumbs are also present on that view and can be used for navigation.
Current design of the error state is improvised, likely to be changed once we have some design guidance about it.
Having a modest-size files in a project would lead to a timeout when the project was first initialized. This became apparent when testing delivered `.enso-project` files with some data files. After some digging there was a bug in JGit
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=494323) which meant that adding such files was really slow. The implemented fix is not on by default but even with `--renormalization` turned off I did not see improvement.
In the end it didn't make sense to add `data` directory to our version control, or any other files than those in `src` or some meta files in `.enso`. Not including such files eliminates first-use initialization problems.
# Important Notes
To test, pick an existing Enso project with some data files in it (> 100MB) and remove `.enso/.vcs` directory. Previously it would timeout on first try (and work in successive runs). Now it works even on the first try.
The crash:
```

- Implements https://github.com/enso-org/cloud-v2/issues/631
- Tests for dashboard (`app/ide-desktop/lib/dashboard/`):
- End-to-end tests
- Unit tests
- Component tests
The purpose of this PR is to introduce the testing framework - more tests can be added later in separate PRs.
# Important Notes
To test, run `npm run test` in `app/ide-desktop`, or `app/ide-desktop/lib/dashboard/`. All tests should pass.
Individual test types can be run using `npm run test-unit`, `npm run test-component` and `npm run test-e2e` in `app/ide-desktop/lib/dashboard/`.
Individual end-to-end tests can be run using `npx playwright test -c playwright-e2e.config.ts test-e2e/<file name>.spec.ts` in `app/ide-desktop/lib/dashboard/`.
End-to-end tests require internet access to pass (for things like fonts).
